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 and the TMUX4052-Q1 is a 4:1,

2-channel multiplexer. The devices work with a single

supply (5 V to 24 V), dual supplies (up 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 battery testers to appliances.

The TMUX405x-Q1 devices support bidirectional

analog signals on the source (Sx) and drain (Dx) pins

ranging from VSS to VDD. All logic inputs have 1.8 V

logic compatible thresholds, which is compatible for

both TTL and CMOS logic when operating with a valid

supply voltage.
