TMUX1101/TMUX1102 Precision Analog Switches

Texas Instruments TMUX1101/TMUX1102 Precision Analog Switches are complementary metal-oxide semiconductor (CMOS) single-pole, single-throw (SPST) switches. A wide operating supply of 1.08V to 5.5V allows for use in a broad array of applications, from medical equipment to industrial systems. These devices support bidirectional analog and digital signals on the source (S) and drain (D) pins ranging from GND to VDD. The logic control input (SEL) has 1.8V logic-compatible thresholds, ensuring both TTL and CMOS logic compatibility when operating within the valid supply voltage range. The switch of the Texas Instruments TMUX1101 is turned on when SEL is Logic 1, while TMUX1102 is turned on when SEL is Logic 0. Fail-safe logic circuitry allows voltages on the SEL pin to be applied before the supply pin, protecting the device from potential damage.
