Low-Voltage, Single and Dual Supply, Dual

4 to 1 Multiplexer Analog Switch with

Latch

The Intersil ISL43841 device is a precision, bidirectional,

analog switches configured as a a dual 4 channel multiplexer/

demultiplexer designed to operate from a single +2V to +12V

supply or from a

pin to lock in the last switch address.

ON resistance of 39Ω with a

+3.3V supply. Each switch can handle rail to rail analog

signals. The off-leakage current is only 0.1nA at +25

2.5nA at +85

All digital inputs have 0.8V to 2.4V logic thresholds, ensuring

TTL/CMOS logic compatibility when using a single 3.3V or

+5V supply or dual

The ISL43841 is a dual 4 to 1 multiplexer device. Table 1

summarizes the performance of this part.
