Overview
The 74HCT253D,653 is a dual 4-bit multiplexer produced by Nexperia USA Inc. This integrated circuit is part of the 74HCT series and is designed to handle multiple input signals and select one of them to be output based on the select inputs. Each multiplexer has four binary inputs (nI0 to nI3), an output enable input (nOE), and shared select inputs (S0 and S1). The device is suitable for a wide range of applications due to its versatile functionality and robust specifications.
