Ultra Low ON-Resistance, Low-Voltage,
Single Supply, Dual 4 to 1 Analog
Multiplexer
The Intersil ISL43L840 device is a precision, bidirectional,
analog switches configured as a dual 4-channel
multiplexer/demultiplexer, designed to operate from a single
+1.6V to +3.6V supply.
ON resistance is 0.5with a +3V supply and 0.62with a
single +1.8V supply. Each switch can handle rail to rail
analog signals. The off-leakage current is only 4nA max at
+25°C and 30nA max at +85°C with a +3.3V supply.
All digital inputs are 1.8V logic-compatible when using a
single +3V supply.
The ISL43L840 is a dual 4 to 1 multiplexer device that is
offered in a 16 Ld TSSOP and 16 Ld 3x3 QFN packages.
Table 1 summarizes the performance of this family.

Detailed Description
The ISL43L840 analog switches offer precise switching
capability from a single 1.6V to 3.6V supply with low on-
resistance (0.5) and high speed operation (tRANS = 19ns).
The device is especially well-suited to portable battery
powered equipment thanks to the low operating supply
voltage (1.6V), low power consumption (0.2µW), and low
leakage currents (60nA max). High frequency applications
also benefit from the wide bandwidth, and the very high off
isolation and crosstalk rejection.
Supply Sequencing And Overvoltage Protection
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 8). 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. If these
6
conditions cannot be guaranteed, then one of the following
two protection methods should be employed.
Logic inputs can easily be protected by adding a 1k
resistor in series with the input (see Figure 8). 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 method is not applicable for the signal path inputs.
Adding a series resistor to the switch input defeats the
purpose of using a low RON switch, so two small signal
diodes can be added in series with the supply pins to provide
overvoltage protection for all pins (see Figure 8). These
additional diodes limit the analog signal from 1V below V+ to
1V above GND. The low leakage current performance is
unaffected by this approach, but the switch signal range is
