3 Description

The TMUX1208 and TMUX1209 are general purpose

complementary metal-oxide semiconductor (CMOS)

multiplexers (MUX). The TMUX1208 offers 8:1 singleended

channels, while the TMUX1209 offers

differential 4:1 or dual 4:1 single-ended channels.

Wide operating supply of 1.08 V to 5.5 V allows for

use in a broad array of applications from personal

electronics to building automation applications. The

device supports bidirectional analog and digital

signals on the source (Sx) and drain (D) pins ranging

from GND to VDD.

All logic inputs have 1.8 V logic compatible

thresholds, ensuring both TTL and CMOS logic

compatibility when operating in the valid supply

voltage range. Fail-Safe Logic circuitry allows

voltages on the control pins to be applied before the

supply pin, protecting the device from potential

damage.
