Overview
The 74HC251DB,118 from Nexperia USA Inc. is an 8-input multiplexer with 3-state output, designed to select one of eight binary inputs and route it to the complementary outputs (Y and Y'). This IC is part of the 74HC series, known for its CMOS technology and low power dissipation.
The device features a wide supply voltage range from 2.0 V to 6.0 V, making it versatile for various applications. It includes an output enable input (OE) that, when set to HIGH, causes the outputs to assume a high-impedance OFF-state. The 74HC251DB,118 is packaged in a 16-SSOP (0.209", 5.30mm Width) case and is suitable for surface mount applications.
