3-to-8-line Decoder/Demultiplexer with Address Latch

Description

The HD74HCT137 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. Output enable controls, G₁

and G₂, control the state of the outputs independently of the select or latch-enable inputs.

All of the outputs are high unless G₁is high and G₂is low. The HD74HCT137 is ideally suited for the

implementation of glitchfree decoders in stored-address applications in bus oriented systems.

Features

•

LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility

High Speed Operation: t_pd(A, B, C to Y) = 18 ns typ (C_L= 50 pF)

High Output Current: Fanout of 10 LSTTL Loads

Wide Operating Voltage: V_CC= 4.5 to 5.5 V

Low Input Current: 1 µA max

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