Overview
The 74HC251D-Q100 is an 8-bit multiplexer integrated circuit produced by Nexperia, which was previously part of NXP Semiconductors. This device features eight binary inputs (I0 to I7), three select inputs (S0 to S2), and an output enable input (OE). It is designed to select one of the eight binary inputs and route it to the complementary outputs (Y and Y'). A HIGH on the OE input causes the outputs to assume a high-impedance OFF-state. This component is widely used in various electronic systems due to its versatility and robust specifications.
