TMUX130x/TMUX130x-Q1 CMOS Multiplexers

Texas Instruments TMUX130x/TMUX130x-Q1 General Purpose CMOS Multiplexers (MUX) support bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins ranging from GND to V_DD. The TMUX1308/TMUX1308-Q1 is an 8:1, 1-channel (single-ended) MUX, while the TMUX1309/TMUX1309-Q1 is a 4:1, 2-channel (differential) MUX. The TMUX13xx devices have an internal injection current control feature, eliminating the need for external diode and resistor networks to protect the switch and keep the input signals within the supply voltage. The internal injection current control circuitry allows signals on disabled signal paths to exceed the supply voltage without affecting the signal of the enabled signal path. Additionally, the TMUX130x/TMUX130x-Q1 devices do not have any internal diode path to the supply pin, eliminating the risk of damaging components connected to the supply pin or providing unintended power to the supply rail.
