54HC139 - Dual 2-Line To 4-Line Decoders/Demultiplexers

Datasheet Summary

Description

The SNx4HC139 contains two two-to-four decoders with one active low output strobe G.

When the outputs of one channel are gated by the strobe input, they are all forced into the high state.

Features

Targeted specifically for high-speed memory decoders and data-transmission systems.
Wide operating voltage range of 2 V to 6 V.
Outputs can drive up to 10 LSTTL loads.
Low power consumption, 80-μA max ICC.
Typical tpd = 10 ns.
±4-mA output drive at 5 V.
Low input current of 1 μA max.
Incorporate two enable inputs to simplify cascading and/or data reception xA0 xA1 2.
