HD74HC137 Datasheet 3-to-8-line Decoder/demultiplexer

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC137 3-to-8-line Decoder/Demultiplexer with Address Latch.

General Description

The HD74HC137 implements a three-to-eight line decoder with latches on the three address inputs.

When GL goes from low to high, the address present at the select inputs (A, B and C) is stored in the latches.

As long as GL remains high no address changes will be recognized.

Key Features

  • High Speed Operation: tpd (A, B, C to Y) = 16.5 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) HD74HC137 Function Table Inputs Enable GL X X L L L L L L L L H G1 X L H H H H H H H H H G2 H X L L L L L L L L L Select C X X L L L L H H H H X B X X L L H H L L H H X A X X L H L H L H L H X Outputs.
