Overview
The CD74HCT154M96 is a high-speed CMOS logic 4-to-16 line decoder/demultiplexer produced by Texas Instruments. This integrated circuit is part of the 74HCT series and is designed to perform both decoding and demultiplexing functions. It features two enable inputs, E1 and E2, which allow for flexible control over the output lines. A high state on either enable input forces all output lines into a high state. The device uses four input lines (A0 to A3) to select one of the 16 output lines (Y0 to Y15), making it versatile for various digital circuit applications.
