Data Sheet

June 30, 2006

FN6212.1

Ultra Low ON-Resistance, Low-Voltage,

Single Supply, Differential 4 to 1 Analog

Multiplexer

The Intersil ISL43L841 device contains precision,

bidirectional, analog switches configured as a differential

4-channel multiplexer/demultiplexer. It is designed to operate

from a single +1.65V to +4.5V supply. The device has an

inhibit pin to simultaneously open all signal paths. With a

supply voltage of 4.2V and logic high voltage of 2.85V at the

logic inputs, the part draws only 20碌A max of ICC current.

ON resistance is 0.47鈩?with a +4.3V supply and 0.65鈩?with

a single +1.8V supply. Each switch can handle rail to rail

analog signals. A channel can handle 300mA of continuous

current. The part has low quiescent power consumption of

0.23碌W max.

All digital inputs are 1.8V logic-compatible when using a

single +3V supply.

The ISL43L841 is a differential 4 to 1 multiplexer device that is

offered in a 16 Ld 3x3 TQFN package.

Table 1 summarizes the performance of this family.
