Overview
The TMUX1101DCKR is a precision complementary metal-oxide semiconductor (CMOS) single-pole, single-throw (SPST) switch produced by Texas Instruments. This device is part of the TMUX110x family, known for its wide operating supply range of 1.08V to 5.5V, making it suitable for a broad array of applications from medical equipment to industrial systems. The TMUX1101 supports 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 compatibility with both TTL and CMOS logic. The switch is turned on when the SEL pin is at Logic 1, and the device features fail-safe logic to protect against potential damage by allowing voltages on the SEL pin to be applied before the supply pin.
