Overview
The 74HC154BQ is a 4-to-16 line decoder/demultiplexer produced by Nexperia USA Inc. This high-speed Si-gate CMOS device 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 (E0 and E1) inputs, allowing for flexible operation as either a decoder or a demultiplexer. The device is pin compatible with Low-power Schottky TTL (LSTTL) and operates within a wide supply voltage range from 2.0 V to 6.0 V, making it versatile for various electronic designs.
