Automotive, ±12-V, 4:1 two-channel multiplexer with 1.8-V compatible logic

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 V DD = 12 V, V SS = –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 V SS to V DD. 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.
