Description for the TMUX1309

The TMUX1308 and TMUX1309 are general purpose complementary metal-oxidesemiconductor (CMOS) multiplexers (MUX). The TMUX1308 is an8:1,
1-channel (single-ended) mux, while the TMUX1309 is a 4:1, 2-channel(differential) mux. The devices support bidirectional analog and digital signals on the source (Sx)and drain (Dx) pins ranging from GND to VDD.

The TMUX13xx devices have an internal injection current control featurewhich eliminates the need for external diode and resistor networks typically used to protect theswitch and keep the input signals within the supply voltage. The internal injection current controlcircuitry allows signals on disabled signal paths to exceed the supply voltage without affectingthe signal of the enabled signal path. Additionally, the TMUX13xx devices do nothave any internal diode path to the supply pin, which eliminates the risk of damaging componentsconnected to the supply pin, or providing unintended power to the supply rail.

All logic inputs have 1.8 V logic compatible thresholds, ensuring both TTL and CMOSlogic compatibility when operating with a valid supply voltage. Fail-Safe Logic circuitry allows voltages on the control pinsto be applied before the supply pin, protecting the device from potential damage.
