8 Detailed Description

8.3 Feature Description
8.3.1 Open-Drain CMOS Outputs
This device includes open-drain CMOS outputs. Open-drain outputs can only drive the output low. When in the
high logical state, open-drain outputs will be in a high-impedance state. The drive capability of this device may
create fast edges into light loads so routing and load conditions should be considered to prevent ringing.
Additionally, the outputs of this device are capable of driving larger currents than the device can sustain without
being damaged. It is important for the output power of the device to be limited to avoid damage due to
overcurrent. The electrical and thermal limits defined in the Absolute Maximum Ratings must be followed at all
times.
When placed into the high-impedance state, the output will neither source nor sink current, with the exception of
minor leakage current as defined in the Electrical Characteristics table. In the high-impedance state, the output
voltage is not controlled by the device and is dependent on external factors. If no other drivers are connected to
the node, then this is known as a floating node and the voltage is unknown. A pull-up resistor can be connected
to the output to provide a known voltage at the output while it is in the high-impedance state. The value of the
resistor will depend on multiple factors, including parasitic capacitance and power consumption limitations.
Typically, a 10 kΩ resistor can be used to meet these requirements.
Unused open-drain CMOS outputs should be left disconnected.
8.3.2 CMOS Schmitt-Trigger Inputs
Standard CMOS inputs are high impedance and are typically modeled as a resistor from the input to ground in
parallel with the input capacitance given in the Electrical Characterisitcs. The worst case resistance is calculated
with the maximum input voltage, given in the Absolute Maximum Ratings, and the maximum input leakage
current, given in the Electrical Characteristics, using ohm's law (R = V ÷ I).
The Schmitt-trigger input architecture provides hysteresis as defined by ΔVT in the Electrical Characterisitcs,
which makes this device extremely tolerant to slow or noisy inputs. While the inputs can be driven much slower
than standard CMOS inputs, it is still recommended to properly terminate unused inputs. Driving the inputs
slowly will also increase dynamic current consumption of the device. For additional information regarding
Schmitt-trigger inputs, please see Understanding Schmitt Triggers.

9 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification, and TI
does not warrant its accuracy or completeness. TI’s customers are responsible for determining
suitability of components for their purposes. Customers should validate and test their design
implementation to confirm system functionality.
9.1 Application Information
In this application, an open-drain XNOR is used to control a clock source polarity. A Low on the control input will
invert the signal. The Schmitt-trigger inputs will help mitigate noise on the clock signal and will allow for
additional filtering.

9.2.1 Design Requirements
9.2.1.1 Power Considerations
Ensure the desired supply voltage is within the range specified in the Recommended Operating Conditions. The
supply voltage sets the device's electrical characteristics as described in the Electrical Characterisitcs.
The ground must be capable of sinking current equal to the total current to be sunk by all outputs of the
SN74HCS266 plus the maximum supply current, ICC, listed in Electrical Characterisitcs. The logic device can
only sink as much current as is provided by the external pull-up resistor or other supply source. Be sure not to
exceed the maximum total current through GND listed in the Absolute Maximum Ratings.
Total power consumption can be calculated using the information provided in CMOS Power Consumption and C
pd Calculation.
Thermal increase can be calculated using the information provided in Thermal Characteristics of Standard Linear
and Logic (SLL) Packages and Devices.
CAUTION
The maximum junction temperature, T J(max) listed in the Absolute Maximum Ratings, is an
additional limitation to prevent damage to the device. Do not violate any values listed in the Absolute
Maximum Ratings. These limits are provided to prevent damage to the device.
9.2.1.2 Input Considerations
Input signals must cross Vt-(min) to be considered a logic LOW, and Vt+(max) to be considered a logic HIGH. Do
not exceed the maximum input voltage range found in the Absolute Maximum Ratings.
Unused inputs must be terminated to either V CC or ground. These can be directly terminated if the input is
completely unused, or they can be connected with a pull-up or pull-down resistor if the input is to be used
sometimes, but not always. A pull-up resistor is used for a default state of HIGH, and a pull-down resistor is used
for a default state of LOW. The resistor size is limited by drive current of the controller, leakage current into the
SN74HCS266, as specified in the Electrical Characterisitcs, and the desired input transition rate. A 10-kΩ
resistor value is often used due to these factors.

SN74HCS266
SCLS780A – JUNE 2020 – REVISED OCTOBER 2020

The SN74HCS266 has no input signal transition rate requirements because it has Schmitt-trigger inputs.
Another benefit to having Schmitt-trigger inputs is the ability to reject noise. Noise with a large enough amplitude
can still cause issues. To know how much noise is too much, please refer to the ΔVT(min) in the Electrical
Characterisitcs. This hysteresis value will provide the peak-to-peak limit.
Unlike what happens with standard CMOS inputs, Schmitt-trigger inputs can be held at any valid value without
causing huge increases in power consumption. The typical additional current caused by holding an input at a
value other than VCC or ground is plotted in the Typical Characteristics.
Refer to the Feature Description for additional information regarding the inputs for this device.
9.2.1.3 Output Considerations
The ground voltage is used to produce the output LOW voltage. Sinking current into the output will increase the
output voltage as specified by the VOL specification in the Electrical Characterisitcs. The plot in Section 6.8
provides a typical relationship between output voltage and current for this device.
Open-drain outputs can be directly connected together to produce a wired-AND. This is possible because the
outputs cannot source current, and thus can never be in bus-contention.
Unused outputs can be left floating. Do not connect outputs directly to VCC or ground.
Refer to Feature Description for additional information regarding the outputs for this device.
9.2.2 Detailed Design Procedure
1. Add a decoupling capacitor from VCC to GND. The capacitor needs to be placed physically close to the
device and electrically close to both the VCC and GND pins. An example layout is shown in the Section 11.
2. Ensure the capacitive load at the output is ≤ 70 pF. This is not a hard limit, however it will ensure optimal
performance. This can be accomplished by providing short, appropriately sized traces from the SN74HCS266
to the receiving device.
3. Ensure the resistive load at the output is larger than (VCC / IO(max)) Ω. This will ensure that the maximum
output current from the Absolute Maximum Ratings is not violated. Most CMOS inputs have a resistive load
measured in megaohms; much larger than the minimum calculated above.
4. Thermal issues are rarely a concern for logic gates, however the power consumption and thermal increase
can be calculated using the steps provided in the application report, CMOS Power Consumption and Cpd

10 Power Supply Recommendations
The power supply can be any voltage between the minimum and maximum supply voltage rating located in the
Recommended Operating Conditions. Each V CC terminal should have a bypass capacitor to prevent power
disturbance. A 0.1-μF capacitor is recommended for this device. It is acceptable to parallel multiple bypass caps
to reject different frequencies of noise. The 0.1-μF and 1-μF capacitors are commonly used in parallel. The
bypass capacitor should be installed as close to the power terminal as possible for best results, as shown in
Figure 11-1.
11 Layout
11.1 Layout Guidelines
When using multiple-input and multiple-channel logic devices inputs must not ever be left floating. In many
cases, functions or parts of functions of digital logic devices are unused; for example, when only two inputs of a
triple-input AND gate are used. Such unused input pins must not be left unconnected because the undefined
voltages at the outside connections result in undefined operational states. All unused inputs of digital logic
devices must be connected to a logic high or logic low voltage, as defined by the input voltage specifications, to
prevent them from floating. The logic level that must be applied to any particular unused input depends on the
function of the device. Generally, the inputs are tied to GND or VCC, whichever makes more sense for the logic
function or is more convenient.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
