TMUX13xx-Q1 5-V, Bidirectional 8:1, 1-Channel and 4:1, 2-Channel  
Multiplexers with Injection Current Control  
1 Features  
3 Description  
AEC-Q100 Qualified for Automotive Applications  
The TMUX1308-Q1 and TMUX1309-Q1 are general  
purpose complementary metal-oxide semiconductor  
(CMOS) multiplexers (MUX). The TMUX1308-Q1 is  
an 8:1, 1-channel (single-ended) mux, while the  
TMUX1309-Q1 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  
– Device Temperature Grade 1: –40°C to 125°C  
Ambient Operating Temperature  
Injection Current Control  
Back-powering Protection  
– No ESD Diode Path to VDD  
Wide Supply Range: 1.62 V to 5.5 V  
Low Capacitance  
Bidirectional Signal Path  
Rail-to-Rail Operation  
1.8 V Logic Compatible  
Fail-safe Logic  
Break-before-make Switching  
Functional Safety-Capable  
Documentation Available to Aid Functional  
Safety System Design  
from GND to VDD  
.
The TMUX13xx-Q1 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 signal  
paths to exceed the supply voltage without affecting  
the signal of the enabled signal path. Additionally, the  
TMUX13xx-Q1 devices do 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 supply rail.  
TMUX1308-Q1 - Pin Compatible with:  
– Industry Standard 4051 and 4851 Multiplexers  
TMUX1309-Q1 - Pin Compatible with:  
– Industry Standard 4052 and 4852 Multiplexers  
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.
