Overview
The TMUX4157N, produced by Texas Instruments, is a general-purpose 2:1 single-pole double-throw (SPDT) switch designed to operate with negative supply voltages. This device supports a supply voltage range from -4 V to -12 V and is capable of handling bidirectional analog and digital signals. The TMUX4157N features 1.8 V logic compatible control inputs, making it compatible with typical control logic circuitry such as GPIO signals. It is particularly suited for applications requiring fast switching between two different voltage inputs, such as in wireless communications, GaN power amplifier gate switching, and remote radio units.
