3 Description

The TMUX405x-Q1 devices are general purpose

complementary metal-oxide semiconductor (CMOS)

multiplexers (MUX). The TMUX4051-Q1 is an 8:1,

1-channel multiplexer, the TMUX4052-Q1 is a 4:1, 2-

channel multiplexer. The devices work with a single

supply (3 V to 24 V), dual supplies (±3 V to ±12 V),

or asymmetric supplies (such as VDD = 12 V, VSS

= –5 V). The wide supply voltage range allows the

TMUX405x-Q1 devices to be used in a broad array of

applications from factory automation to appliances.

The TMUX405x-Q1 devices support bidirectional

analog and digital signals on the source (Sx) and

drain (Dx) pins ranging from VSS to VDD. All logic

inputs have 1.8 V logic compatible thresholds,

ensuring both TTL and CMOS logic compatibility

when operating with a valid supply voltage.
