概述
Description
SN74LVC1G3157YZPR is a TI single 2-to-1 data selector/multiplexer in the LVC1G family. It multiplexes two inputs (I0 and I1) to a single output (Y) based on a select input (S). It’s designed for low-power, high-speed digital logic and operates from a 1.65 V to 3.6 V supply. The YZPR suffix denotes a RoHS-compliant packaging option (small, tape-and-reel). Typical uses include routing a data signal within compact, low-voltage logic circuits and bus-sharing paths in mixed-logic designs.
