Overview
The 74HCT4052PW/S400118, produced by NXP USA Inc., is a dual single-pole quad-throw analog switch (2 × SP4T) designed for use in both analog and digital 4:1 multiplexer/demultiplexer applications. This component is part of the 74HCT series, which is known for its compatibility with TTL logic levels. Each switch features four independent inputs/outputs (nY0, nY1, nY2, and nY3) and a common input/output (nZ), along with a digital enable input (E) and two digital select inputs (S0 and S1) that are common to both switches. When the enable input (E) is HIGH, the switches are turned off, allowing for precise control over signal routing.
