Product Summary
The 74HC139 is a dual 2-to-4 line decoder/demultiplexer. The 74HC139 is a high-speed Si-gate CMOS device and are pin compatible with low power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. This 74HC139 has two independent decoders, each accepting two binary weighted inputs (nA0 and nA1) and providing four mutually exclusive active LOW outputs (nY0 to nY3).
Parametrics
74HC139 absolute maximum ratings: (1)tPHL/ tPLH propagation delay CL = 15pF; VCC = 5 V; (2)nAn to nYn: 13 ns; (3)nE3 to nYn: 13 ns; (4)CI input capacitance: 3.5pF; (5)CPD power dissipation capacitance per multiplexer: 44pF.
