3 Description

The TMUX1247 is a general purpose complementary

metal-oxide semiconductor (CMOS) single-pole

double-throw (SPDT) switch. The TMUX1247

switches between two source inputs based on the

state of the SEL pin. Wide operating supply of 1.08 V

to 5.5 V allows for use in a broad array of

applications from personal electronics to building

automation. 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 4 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.
