3 Description

The TMUX1119 is a complementary metal-oxide

semiconductor (CMOS) single-pole double-throw (2:1)

switch. Wide operating supply of 1.08V to 5.5V allows

for use in a broad array of applications from medical

equipment to industrial systems. The device supports

bidirectional analog and digital signals on the source

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

All logic inputs have 1.8V logic compatible thresholds,

allowing for 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.

The TMUX1119 is part of the precision switches and

multiplexers family of devices. These devices have

very low on and off leakage currents and low charge

injection, allowing them to be used in high precision

measurement applications. A low supply current of

3nA and small package options enable use in portable

applications.
