5-V, low-leakage-current, 1:1 (SPST) precision switch (active high)

 

Description

The TMUX1101 and TMUX1102 are precision complementary metal-oxide semiconductor (CMOS) single-pole, single-throw (SPST) switches. Wide operating supply of 1.08 V to 5.5 V allows for use in a broad array of applications from medical equipment to industrial systems. The devices support bidirectional analog and digital signals on the source (S) and drain (D) pins ranging from GND to VDD.

The logic control input (SEL) has 1.8 V logic compatible thresholds, ensuring both TTL and CMOS logic compatibility when operating within the valid supply voltage range. The switch of the TMUX1101 is turned on when SEL is Logic 1, while TMUX1102 is turned on when SEL is Logic 0. Fail-Safe Logic circuitry allows voltages on the SEL pin to be applied before the supply pin, protecting the device from potential damage.

The TMUX110x 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
3 nA and small package options enable use in portable applications.
