Texas Instruments TMUX113x 3 or 4-Channel Precision Switches

Texas Instruments TMUX113x 3 or 4-Channel Precision Switches are 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. A wide operating supply of 1.08V to 5.5V, or ±2.75V dual supply, allows for use in various applications, from medical equipment to industrial systems. Each 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 1.8V logic-compatible thresholds, ensuring 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 Texas Instruments TMUX113x 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 8nA enables use in portable applications.
