Texas Instruments  PTMUX1134PWR

The TMUX113x devices are precision complementary metal-oxidesemiconductor (CMOS) switches with multiple channels. The TMUX1133 is a 2:1,single-pole double-throw (SPDT), configuration with three independently controlled channels and anEN pin to enable or disable all three switches. TheTMUX1134 contains four independently controlled SPDT switches. Wide operatingsupply of 1.08 V to 5.5 V, or ±2.75 V dual supply, allows for use in a broad array of applicationsfrom medical equipment to industrial systems. The device supports bidirectional analog and digitalsignals on the source (Sx) and drain (Dx) pins ranging from VSS toVDD. For single supply applications VSS can beconnected to GND.

All logic inputs have 1.8 V logic compatiblethresholds, ensuring both TTL and CMOS logic compatibility when operating in the valid supplyvoltage range. Fail-Safe Logic circuitry allows voltageson the control pins to be applied before the supply pin, protecting the device from potentialdamage.

The TMUX113x 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
8 nA enables use in portable applications.
