Overview
The 74HCT154D,652, produced by Nexperia USA Inc., is a 4-to-16 line decoder/demultiplexer integrated circuit. This device is part of the 74HCT series, which is known for its compatibility with TTL (Transistor-Transistor Logic) input levels. It decodes four binary weighted address inputs (A0 to A3) into sixteen mutually exclusive outputs (Y0 to Y15), making it versatile for various digital circuit applications. The device also features two input enable (E0 and E1) inputs, allowing for flexible control over the output states.
