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
equipment that benefits from low rON (0.35Ω) and fast
switching speeds (tON = 14ns, tOFF = 6ns). The digital logic
input is 1.8V logic-compatible when using a single +3V supply.
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
dual 2-to-1 multiplexer. The ISL84762 is pin compatible with
the MAX4762.

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 (0.39Ω) and high speed operation
(tON = 14ns, tOFF = 6ns). 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 rON flatness provide very low insertion loss and distortion
to applications that require signal reproduction.
External V+ Series Resistor
For improved ESD and latch-up immunity, Intersil
recommends adding a 100Ω resistor in series with the V+
power supply pin of the ISL84762 IC (see Figure 8).

GND
Repeat test for all switches.
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.
Under normal operation, the sub-microamp IDD current of
the IC produces an insignificant voltage drop across the
100Ω series resistor resulting in no impact to switch
operation or performance.

Supply Sequencing and Overvoltage Protection
FIGURE 9. OVERVOLTAGE PROTECTION
Power-Supply Considerations
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 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.
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.
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.
Logic inputs can be protected by adding a 1kΩ 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.
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.
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 rON switch. Connecting Schottky
diodes to the 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 family of switches cannot be operated with bipolar
supplies, because the input switching point becomes
negative in this configuration.

Logic-Level Thresholds
about 68dB in 50Ω 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.
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 VIH level is about 1.27V. This is still below the 1.8V
CMOS 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.
High-Frequency Performance
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 analogsignal-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
In 50Ω 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 this part. At 100kHz, off-Isolation is
