Overview
The 74HC251D-Q100J is an 8-bit multiplexer integrated circuit produced by Nexperia USA Inc. This device is part of the 74HC and 74HCT series, known for their high-speed Si-gate CMOS technology and compatibility with low power Schottky TTL (LSTTL) devices. The 74HC251D-Q100J features eight binary inputs (I0 to I7), three select inputs (S0 to S2), and an output enable input (OE), allowing it to select one of the eight binary inputs and route it to the complementary outputs (Y and Y'). The output enable input can place the outputs in a high-impedance OFF-state when set to HIGH.
