Overview
The 74HC154D,652, produced by Nexperia USA Inc., is a 4-to-16 line decoder/demultiplexer integrated circuit. This device is part of the 74HC family, known for its high-speed CMOS logic. It decodes four binary weighted address inputs (A0 to A3) into sixteen mutually exclusive outputs (Y0 to Y15), making it highly versatile for various digital circuit applications. The device also features two input enable (E0 and E1) inputs, which can force the outputs HIGH when either enable input is HIGH. This functionality allows the device to be used as a 1-to-16 demultiplexer by utilizing one of the enable inputs as the multiplexed data input.
