3 Description

The TMUX1308A and TMUX1309A 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 analog and digital signals on the source (Sx) and drain (Dx) pins ranging from GND to VDD.

The TMUX13xxA devices have an internal injection current control feature, which eliminates the need for external diode and resistor networks typically used to protect the switch and keep the input signals within the supply voltage. The internal injection current control circuitry allows signals on disabled or enabled signal paths to exceed the supply voltage. Disabled channels with voltages above VDD are prevented from affecting the signal of the enabled signal path. Additionally, the TMUX13xxA devices do not have an internal diode path to the supply pin, which eliminates the risk of damaging components connected to the supply pin or providing unintended power to the supply rail.

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