The TMUX1111, TMUX1112, and TMUX1113are precision complementary metal-oxide semiconductor (CMOS) devices that have four independentlyselectable single-pole / single-throw (SPST) switches. Wide operating supply of 1.08 V to 5.5 Vallows for use in a broad array of applications from medical equipment to industrial systems. Thedevice supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pinsranging from GND to VDD.

The switches of the TMUX1111 are turned on with Logic 0 on theappropriate logic control inputs, while Logic 1 is required to turn on switches in theTMUX1112. The four channels of the TMUX1113 are split with twoswitches supporting Logic 0, while the other two switches support Logic 1. TheTMUX1113 exhibits break-before-make switching, allowing the device to be used incross-point switching applications.

The TMUX111x 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 5 nA and small package options enable use in portable applications.
