Texas Instruments TMUX541x 4-Channel (SPST) Switches

Texas Instruments TMUX541x 4-Channel (SPST) Switches are general-purpose, complementary metal-oxide semiconductor (CMOS) switch devices with four independently selectable 1:1, single-pole, single-throw (SPST) switch channels. The devices work with dual supplies (±4.5V to ±25V), a single supply (4.5V to 50V), or asymmetric supplies (such as VDD = 37.5V, VSS = –12.5V). The TMUX541x supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins ranging from VSS to VDD.

The switches of the Texas Instruments TMUX541x are controlled with appropriate logic control inputs on the SELx pins. The TMUX541x exhibits break-before-make switching, enabling the device to be used in cross-point and multiplexing applications.
