The TMUX1204 is a modern complementary metal-oxide semiconductor (CMOS) analog multiplexer (MUX) in a 4:1 single-ended (1-channel) configuration. The TMUX1204 works with a single supply (1.08 V to 5.5 V) which allows for use in a broad array of applications from personal electronics to building automation systems. A low supply current of 10 nA enables use in portable applications.

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.
