Overview
The 74HC154PW,112 is a 4-to-16 line decoder/demultiplexer integrated circuit produced by Nexperia, although it was previously part of NXP Semiconductors' portfolio. This device decodes four binary weighted address inputs (A0 to A3) into sixteen mutually exclusive outputs (Y0 to Y15). It features two input enable (E0 and E1) inputs, where a HIGH on either enable input forces the outputs HIGH. This flexibility allows the device to be used as a 1-to-16 demultiplexer by utilizing one of the enable inputs as the multiplexed data input.
The 74HC154PW,112 operates within a wide supply voltage range of 2.0 V to 6.0 V, making it versatile for various applications. It is known for its CMOS low power dissipation, high noise immunity, and robust latch-up performance.
