Bare Die Product Detail: 54HC139

Decoder/Encoder/Multiplexer:
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 54HC139, Motorola 54HC139, RCA Harris 54HC139 and Texas Instruments SN54HC139, CD54HC139.

Features:
