SN74HCS139 Dual 2- to 4-Line Decoders/Demultiplexers with Schmitt-Trigger Inputs

1 Features

3 Description

•

Wide operating voltage range: 2 V to 6 V

Schmitt-trigger inputs allow for slow or noisy input

signals

Low power consumption

– Typical I_CCof 100 nA

– Typical input leakage current of ±100 nA

±7.8-mA output drive at 6 V

Extended ambient temperature range: –40°C to

+125°C, T_A

The SN74HCS139 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. When the

outputs are not disabled by the strobe input, only the

selected output is low while all others are high.
