double-pole/double-throw (DPDT) analog switches fea-
ture Beyond-the-Rails™ capability that allows signals
from -5.5V to +5.5V to pass without distortion, even when
the power supply is below the signal range. The low on-
resistance (0.25Ω) also makes the device ideal for low-
distortion switching applications, such as audio or video.

Not Applied
When power is not applied, the switches go to a high-
impedance mode and all analog signal ports can with-
stand signals from -5.5V to +5.5V. The switch is controlled
with a single control bit, CB.

ESD Test Conditions
Detailed Description
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents test
methodology and test results.
The MAX14689 is an ultra-small, low on-resistance, high
ESD-protected DPDT switch that operates from a +1.6V
to +5.5V supply, and is designed to pass analog signals
such as AC-biased or DC-biased audio and video sig-

nals. These switches feature the low on-resistance (R
)
ON
Figure 4 shows the Human Body Model. Figure 5 shows
the current waveform it generates when discharged into a
low impedance. This model consists of a 100pF capacitor
charged to the ESD voltage of interest that is then dis-
charged into the device through a 1.5kΩ resistor.
necessary for high-performance switching applications.
The Beyond-the-Rails signal capability of the MAX14689
allows signals below ground and above
out distortion.
to pass with-
VCC
Analog Signal Levels
IEC 61000-4-2
The MAX14689 is bidirectional, allowing NO_, NC_, and
COM_ to be configured as either inputs or outputs. The
topology of the switches allows the signal to drop below
ground without the need of an external negative voltage
supply. Note: The devices can also withstand analog
signal levels of -5.5V to +5.5V when the device is not
powered.
The IEC 61000-4-2 standard covers ESD testing and per-
formance of finished equipment. It does not specifically
refer to integrated circuits. The major difference between
tests done using the HBM and IEC 61000-4-2 is higher
peak current in IEC 61000-4-2, because series resistance
is lower in the IEC 61000-4-2 model. Hence, the ESD
withstand voltage measured to IEC 61000-4-2 is gener-
ally lower than that measured using the HBM. Figure 6
shows the IEC 61000-4-2 model and Figure 7 shows the
current waveform for the ±8kV, IEC 61000-4-2, Level 4,
ESD Contact-Discharge Method.
Digital Control Input
The MAX14689 provides a single-bit control logic input,
CB. CB controls the switch position, as shown in the
Typical Application Circuit/Functional Diagram.
Applications Information
Extended ESD Protection
ESD-protection structures are incorporated on all pins to
protect against electrostatic discharges up to ±2kV (HBM)
encountered during handling and assembly. COM1 and
COM2 are further protected against ESD up to ±15kV
(HBM), ±10kV (Air-Gap Discharge), and ±8kV (Contact
Discharge) without damage. NO_ and NC_ are protected
against ESD up to ±15kV (HBM) without damage. The
ESD structures withstand high ESD both in normal opera-
tion and when the device is powered down. After an ESD
event, the devices continue to function without latchup.
