Overview
The TMUX1101DBVR, produced by Texas Instruments, is a precision complementary metal-oxide semiconductor (CMOS) single-pole, single-throw (SPST) switch. This device is part of the TMUX110x family and is 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 TMUX1101DBVR supports bidirectional analog and digital signals on the source (S) and drain (D) 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, ensuring protection against potential damage by allowing voltages on the SEL pin to be applied before the supply pin.
