Overview
The 74HCT238D,653 is a 3-to-8 line decoder/demultiplexer integrated circuit (IC) produced by Nexperia USA Inc. This device is part of the 74HCT series and is designed to decode three binary weighted address inputs (A0, A1, and A2) into eight mutually exclusive outputs (Y0 to Y7). It can also function as an eight-output demultiplexer by using one of the active LOW enable inputs as the data input and the remaining enable inputs as strobes. The 74HCT238D,653 is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package, making it suitable for a variety of applications requiring compact and efficient logic functions.
