Overview
The 74HC157DB,118, produced by Nexperia USA Inc., is a quad 2-input multiplexer integrated circuit. This device is part of the 74HC series, known for its high-performance and low-power CMOS logic family. The 74HC157 is designed to select one of two data sources based on the state of the select input (S), and it features an enable input (E) that can force all outputs to a low state when high. This multiplexer is available in various packages, including the SSOP16 (SOT338-1) package for the 74HC157DB,118 variant.
