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

The switch of the TMUX1101 is turned on with a Logic 1 on the selectpin, while a Logic 0 is required to turn on switch in the TMUX1102.

The TMUX110x devices are part of the precision switches andmultiplexers family. These devices have very low on and off leakage currents and low chargeinjection, allowing them to be used in high precision measurement applications. A low supplycurrent of 3 nA and small package options enable use in portable applications.
