SN74HCS139-Q1  
SCLS812 – SEPTEMBER 2020  
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,  
TA  
– 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 ICC of 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.
