Overview
The TMUX7212RUMR is a precision, 4-channel, single-pole, single-throw (SPST) analog switch produced by Texas Instruments. This device is part of the TMUX721x family, which includes the TMUX7211 and TMUX7213 models. The TMUX7212 is specifically designed with logic high active control inputs, making it suitable for a wide range of applications that require high precision and reliability.
The TMUX7212 operates with a single supply voltage ranging from 4.5V to 44V or dual supplies from ±4.5V to ±22V, and it supports bidirectional analog and digital signals. This versatility, combined with its low on-resistance and high current support, makes it an ideal choice for various automotive and industrial applications.
