3 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 V
DD
.
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.
