Overview
The 74HCT4053PW,112 is a triple single-pole double-throw (SPDT) analog switch produced by Nexperia USA Inc. This integrated circuit is designed for use in both analog and digital 2:1 multiplexer/demultiplexer applications. It features three independent switches, each with a digital select input, two independent inputs/outputs, and a common input/output. A digital enable input is common to all switches, allowing them to be turned off when set to HIGH. The device is part of the 74HCT family, known for its compatibility with TTL logic levels and its ability to handle a wide range of analog input voltages.
