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.
