Overview
The 74HCT4053PW/AUJ is a triple 2-channel analog multiplexer/demultiplexer produced by Nexperia (previously part of NXP USA Inc.). This component is a triple single-pole double-throw (SPDT) analog switch, making it suitable for both analog and digital 2:1 multiplexer/demultiplexer applications. Each switch features a digital select input, two independent inputs/outputs, and a common input/output, along with a digital enable input that controls all switches.
