HD74HC139 Datasheet Dual 2-to-4-line Decoders/demultiplexers

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC139 Dual 2-to-4-line Decoders/Demultiplexers.

General 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.

Key Features

  • High Speed Operation: tpd (A, B to Y, 4 levels) = 14 ns typ (C L = 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) Function Table Inputs Enable G H L L L L Select B X L L H H A X L H L H Outputs Y0 H L H H H Y1 H H L H H Y2 H H H L H Y3 H H H H L HD74HC139 Pin Arrangement Enable 1G 1 1A 2 Select 1B 3 1Y0 4.
