3 Description

The TMUX113x devices are precision complementary

metal-oxide semiconductor (CMOS) switches with

multiple channels. The TMUX1133 is a 2:1, singlepole

double-throw (SPDT), configuration with three

independently controlled channels and an EN pin

to enable or disable all three switches. The

TMUX1134 contains four independently controlled

SPDT switches. Wide operating supply of 1.08V to

5.5V, or ±2.75V dual supply, 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 (Dx) pins ranging from VSS to VDD. For single

supply applications VSS must be connected to GND.

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 TMUX113x devices are part of the precision

switches and multiplexers family. 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

8nA enables use in portable applications.
