TMUX130xA/TMUX130xA-Q1 CMOS Multiplexers

Texas Instruments TMUX130xA/TMUX130xA-Q1 CMOS Multiplexers are general-purpose complementary metal-oxide semiconductor (CMOS) multiplexers (MUX). The TMUX1308A is an 8:1, 1-channel (single-ended) mux, while the TMUX1309A is a 4:1, 2-channel (differential) mux. The devices support bidirectional digital and analog signals on the drain (Dx) and source (Sx) pins, ranging from GND to V_DD. The Texas Instruments TMUX130xA devices have an internal injection current control feature, eliminating the need for an external diode, and are typically used to keep the input signals within the supply voltage and protect the switch. The internal injection current control circuitry allows signals on disabled or enabled signal paths to exceed the supply voltage. Disabled channels with voltages above V_DD are prevented from affecting the signal of the enabled signal path.
