The TMUX6111, TMUX6112, and TMUX6113 devices are modern complementary metal-oxide semiconductor (CMOS) devices that have four independently selectable single-pole/ single-throw (SPST) switches. The devices work well with dual supplies (±5 V to ±16.5 V), a single supply (10 V to 16.5 V), or asymmetric supplies. All digital inputs have transistor-transistor logic (TTL) compatible thresholds, ensuring TTL/ CMOS logic compatibility.

The switches are turned on with Logic 0 on the digital control inputs in the TMUX6111. Logic 1 is required to turn on switches in the TMUX6112. The TMUX6113 has two switches with similar digital control logic to the TMUX6111 while the logic is inverted on the other two switches. The TMUX6113 exhibits break-before-make switching, allowing the device to be used in the cross-point switching application.

The TMUX611x devices are part of Texas Instruments Precision Switches and Multiplexers family. The devices have very low leakage current and charge injection, allowing them to be used in high-precision measurement applications. Low supply current of 17 µA enables the device usage in portable applications.
