Overview
The TMUX1119DCKR is a complementary metal-oxide semiconductor (CMOS) single-pole double-throw (2:1) switch produced by Texas Instruments. This device is part of the precision switches and multiplexers 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 TMUX1119 supports bidirectional analog and digital signals on the source and drain pins, ranging from GND to VDD, and features 1.8V logic compatible thresholds for both TTL and CMOS logic compatibility. The device is designed with fail-safe logic, protecting it from potential damage by allowing voltages on the control pins to be applied before the supply pin.
