HD74HC139P - Hitachi Semiconductor

HD74HC139

Dual 2-to-4-line Decoders/Demultiplexers

ADE-205-445 (Z)

1st. Edition

Sep. 2000

Description

The HD74HC139 contains two independent two-to-four-line decoders each with a single active low enable

input (1G or 2G). Data on the slect inputs (1A and 1B or 2A and 2B) cause one of the four normally high

outputs to go low.

Features

• High Speed Operation: tpd (A, B to Y, 4 levels) = 14 ns typ (CL = 50 pF)

• High Output Current: Fanout of 10 LSTTL Loads

• Wide Operating Voltage: VCC = 2 V to 6 V

• Low Input Current: 1 µA max

• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
