The TMUX113x devices are precision complementary metal-oxide semiconductor (CMOS) switches with multiple channels. The TMUX1133 is a 2:1, single-pole double-throw (SPDT), configuration with three independently controlled channels and an EN pin to enable or disable all three switches. The TMUX1134 contains four independently controlled SPDT switches. Wide operating supply of 1.08 V to 5.5 V, or ±2.75 V dual supply, allows for use in a broad array of applications from medical equipment to industrial systems. The device supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins ranging from VSS to VDD. For single supply applications VSS must be connected to GND.
All logic inputs have 1.8 V logic compatible thresholds, ensuring both TTL and CMOS logic compatibility when operating in the valid supply voltage range. Fail-Safe Logic circuitry allows voltages on the control pins to be applied before the supply pin, protecting the device from potential damage.
The TMUX113x 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
8 nA enables use in portable applications.
