SN74HCS139-Q1 Automotive Qualified Dual 2- to 4-Line Decoders/Demultiplexers

with Schmitt-Trigger Inputs

1 Features

3 Description

•

AEC-Q100 Qualified for automotive applications:

– Device temperature grade 1: –40°C to +125°C,

T_A

– Device HBM ESD Classification Level 2

– Device CDM ESD Classifcation Level C6

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

The SN74HCS139-Q1 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.
