3 Description
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
(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 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 1.8 V logic
compatible thresholds, ensuring both TTL and CMOS
logic compatibility when operating with a valid supply
voltage.
