Automotive, 5V, 2:1 (SPDT), 1-channel, analog switch, 1.8V compatible logic

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.
