Ultra Low ON-Resistance, Low Voltage, Single Supply, Dual SPDT Analog Switch
The Intersil ISL84762 device is a low ON-resistance, low
voltage, bidirectional, dual single-pole/double-throw (SPDT)
analog switch designed to operate from a single +1.65V to
+3.6V supply. Targeted applications include battery powered

Cell phones, for example, often face ASIC functionality
limitations. The number of analog input or GPIO pins may be
limited and digital geometries are not well suited to analog
switch performance. This part may be used to “mux-in”
additional functionality while reducing ASIC design risk. The
ISL84762 is offered in small form factor packages, alleviating
board space limitations.

The ISL84762 is a committed dual single-pole/double-throw
(SPDT) that consist of two normally open (NO) and two
normally (NC) switches. This configuration can be used as a

FIGURE 6. CROSSTALK TEST CIRCUIT
FIGURE 7. CAPACITANCE TEST CIRCUIT
During an overvoltage transient event, such as occurs during
system level IEC 61000 ESD testing, substrate currents can be
generated in the IC that can trigger parasitic SCR structures to
turn ON, creating a low impedance path from the V+ power
supply to ground. This will result in a significant amount of
current flow in the IC, which can potentially create a latch-up
state or permanently damage the IC. The external V+ resistor
limits the current during this over-stress situation and has been
found to prevent latch-up or destructive damage for many
overvoltage transient events.
Detailed Description
The ISL84762 is a bidirectional, dual single pole/double throw
(SPDT) analog switch that offers precise switching capability
from a single 1.65V to 3.6V supply with low ON-resistance
(0.39) and high speed operation (t
= 14ns, t = 6ns).
ON
OFF
The device is especially well suited for portable battery
powered equipment due to its low operating supply voltage
(1.65V), low power consumption (2.7µW max), low leakage
currents (60nA max), and the tiny, Thin DFN and MSOP
packages. The ultra low ON-resistance and r
flatness provide
ON
very low insertion loss and distortion to applications that require
signal reproduction.
Under normal operation, the sub-microamp I
current of the
DD
IC produces an insignificant voltage drop across the 100
series resistor resulting in no impact to switch operation or
performance.
External V+ Series Resistor
For improved ESD and latch-up immunity, Intersil recommends
adding a 100 resistor in series with the V+ power supply pin
of the ISL84762 IC (see Figure 8).

Power-Supply Considerations
Supply Sequencing and Overvoltage Protection
The ISL84762 construction is typical of most single supply
CMOS analog switches, in that they have two supply pins: V+
and GND. V+ and GND drive the internal CMOS switches and
set their analog voltage limits. Unlike switches with a 4V
maximum supply voltage, the ISL84762 4.8V maximum supply
voltage provides plenty of room for the 10% tolerance of 3.6V
supplies, as well as room for overshoot and noise spikes.
With any CMOS device, proper power supply sequencing is
required to protect the device from excessive input currents
which might permanently damage the IC. All I/O pins contain
ESD protection diodes from the pin to V+ and to GND (see
Figure 9). To prevent forward biasing these diodes, V+ must be
applied before any input signals, and the input signal voltages
must remain between V+ and GND.
The minimum recommended supply voltage is 1.65V but the
part will operate with a supply below 1.5V. It is important to
note that the input signal range, switching times, and
ON-resistance degrade at lower supply voltages. Refer to the
“Electrical Specifications” tables beginning on page 3 and
“Typical Performance Curves” beginning on page 8 for details.
If these conditions cannot be guaranteed, then precautions
must be implemented to prohibit the current and voltage at the
logic pin and signal pins from exceeding the maximum ratings
of the switch. The following two methods can be used to
provided additional protection to limit the current in the event
that the voltage at a signal pin or logic pin goes below ground
or above the V+ rail.
V+ and GND also power the internal logic and level shiftiers.
The level shiftiers convert the input logic levels to switched V+
and GND signals to drive the analog switch gate terminals.
Logic inputs can be protected by adding a 1k resistor in
series with the logic input (see Figure 9). The resistor limits the
input current below the threshold that produces permanent
damage, and the sub-microamp input current produces an
insignificant voltage drop during normal operation.
This family of switches cannot be operated with bipolar
supplies, because the input switching point becomes negative
in this configuration.
This method is not acceptable for the signal path inputs.
Adding a series resistor to the switch input defeats the purpose
of using a low r
switch. Connecting Schottky diodes to the
ON
signal pins as shown in Figure 9 will shunt the fault current to
the supply or to ground thereby protecting the switch. These
Schottky diodes must be sized to handle the expected fault
current.

this part. At 100kHz, off-Isolation is about 68dB in 50
systems, decreasing approximately 20dB per decade as
frequency increases. Higher load impedances decrease off-
Isolation and crosstalk rejection due to the voltage divider
action of the switch OFF impedance and the load impedance.
Logic-Level Thresholds
This switch family is 1.8V CMOS compatible (0.5V and 1.4V)
over a supply range of 2.0V to 3.6V (see Figure 16). At 3.6V
the V level is about 1.27V. This is still below the 1.8V CMOS
IH
guaranteed high output minimum level of 1.4V, but noise
margin is reduced.
Leakage Considerations
The digital input stages draw supply current whenever the
digital input voltage is not at one of the supply rails. Driving the
digital input signals from GND to V+ with a fast transition time
minimizes power dissipation.
Reverse ESD protection diodes are internally connected between
each analog-signal pin and both V+ and GND. One of these
diodes conducts if any analog signal exceeds V+ or GND.
Virtually all the analog leakage current comes from the ESD
diodes to V+ or GND. Although the ESD diodes on a given
signal pin are identical and therefore fairly well balanced, they
are reverse biased differently. Each is biased by either V+ or
GND and the analog signal. This means their leakages will
vary as the signal varies. The difference in the two diode
leakages to the V+ and GND pins constitutes the analog-
signal-path leakage current. All analog leakage current flows
between each pin and one of the supply terminals, not to the
other switch terminal. This is why both sides of a given switch
can show leakage currents of the same or opposite polarity.
There is no connection between the analog signal paths and
High-Frequency Performance
In 50 systems, the signal response is reasonably flat even
past 30MHz with a -3dB bandwidth of 120MHz (see Figure 17).
The frequency response is very consistent over a wide V+
range, and for varying analog signal levels.
An OFF switch acts like a capacitor and passes higher
frequencies with less attenuation, resulting in signal
feedthrough from a switch’s input to its output. Off-Isolation is
the resistance to this feedthrough, while crosstalk indicates the
amount of feedthrough from one switch to another. Figure 18
details the high off-Isolation and crosstalk rejection provided by
