Bare Die Data Sheet: 74HC139

x2 independent 1–of–4 decoders, decoding a 2 bit address to 1–of–4 active–low outputs. Active–low Selects facilitate the demultiplexing & cascading functions. Demultiplexing uses Address inputs to select desired device output & Select as data input.
The device directly replaces legacy National 74HC139, Motorola 74HC139, RCA Harris 74HC139 and Texas Instruments SN74HC139, CD74HC139.
