Description

The TMUX1308-Q1 device is a general purpose complementary metal-oxide semiconductor (CMOS) multiplexer (MUX). The TMUX1308-Q1 offers 8:1 single-ended channels. The device supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins ranging from GND to VDD.

The TMUX13xx-Q1 have an internal injection current control feature which eliminates the need for external diode/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 signal paths to exceed the supply voltage without affecting the signal of the enabled signal path. Additionally, the TMUX1308-Q1 does not have any 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 system supply rail.

All logic inputs have 1.8 V logic compatible thresholds, ensuring 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.
