3 Description

The TMUX1219-Q1 is a general purpose

complementary metal-oxide semiconductor (CMOS)

single-pole double-throw (SPDT) switch. The

TMUX1219-Q1 switches between two source inputs

based on the state of the SEL pin. Wide operating

supply of 1.08V to 5.5V allows for use in a wide

array of automotive applications. The device supports

bidirectional analog and digital signals on the source

Sx) and drain (D) pins ranging from GND to VDD.

A low supply current of 4nA enables use in portable

applications.

All logic inputs have 1.8V 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.
