The TMUX405x devices are general purpose complementary metal-oxide semiconductor (CMOS) multiplexers (MUX). The TMUX4051 is an 8:1, 1-channel multiplexer, the TMUX4052 is a 4:1, 2-channel multiplexer, and the TMUX4053 is 2:1, 3 channel switch. The devices work with a single supply (5V to 24V), dual supplies (up to ±12V), or asymmetric supplies (such as VDD = 12V, VSS = –5V). The wide supply voltage range allows the TMUX405x devices to be used in a broad array of applications from battery testers to appliances.
The TMUX405x devices support bidirectional analog signals on the source (Sx) and drain (Dx) pins ranging from VSS to VDD. All logic inputs have 1.8V logic compatible thresholds, which is compatible for both TTL and CMOS logic when operating with a valid supply voltage.
