Overview
The TMUX6213RUMR from Texas Instruments is a complementary metal-oxide semiconductor (CMOS) switch that belongs to the precision switches and multiplexers family. This device features four independently selectable 1:1, single-pole, single-throw (SPST) switch channels. It is designed to operate with a wide range of supply voltages, including single supply (4.5V to 36V), dual supplies (±4.5V to ±18V), and asymmetric supplies. The TMUX6213RUMR supports bidirectional analog and digital signals and is controlled by 1.8V logic inputs, making it versatile for various high-precision measurement applications.
