Overview
The 74HC253D-Q100,118 is a dual 4-bit multiplexer produced by Nexperia USA Inc. This component is part of the 74HC253 and 74HCT253 series, which are high-speed Si-gate CMOS devices. Each multiplexer has four binary inputs (nI0 to nI3), an output enable input (nOE), and shared select inputs (S0 and S1). The device is designed to select one of the four binary inputs based on the select inputs and route it to the output nY. A HIGH on the nOE input causes the outputs to assume a high-impedance OFF-state, making it suitable for direct interface with system buses.
