Overview
The 74HC154PW,118 is a 4-to-16 line decoder/demultiplexer produced by Nexperia USA Inc. This integrated circuit is designed to decode four binary weighted address inputs (A0 to A3) into sixteen mutually exclusive outputs (Y0 to Y15). It features two input enable inputs (E0 and E1), where a HIGH on either of these inputs forces the outputs HIGH. The device can also be used as a 1-to-16 demultiplexer by utilizing one of the enable inputs as the multiplexed data input. The 74HC154PW is part of the 74HC family, known for its CMOS low power dissipation and high noise immunity.
