TL331-Q1, TL331B-Q1, TL391B-Q1  
SLVS969F – OCTOBER 2009 – REVISED JANUARY 2021  
TL331B-Q1, TL391B-Q1 and TL331-Q1 Automotive Single Comparators  
1 Features

•
•
Qualified for automotive applications  
AEC-Q100 qualified with the following results:  
– Device temperature grade 1: –40°C to 125°C  
ambient operating temperature range (B and Q  
versions)  
– Device temperature grade 3: –40°C to 85°C  
ambient operating temperature range (I  
version)  
– Device HBM ESD classification level 2  
– Device CDM ESD classification level C5  
NEW TL331B-Q1 and TL391B-Q1  
Wide range of supply voltage, 2 V to 36 V  
Low supply-current drain independent of supply  
voltage:  
The TL331B-Q1 and TL391B-Q1 devices are the next  
generation versions of the industry-standard TL331-  
Q1 comparator. These next generation devices  
provide outstanding value for cost-sensitive  
applications, with features including lower offset  
voltage, higher supply voltage capability, lower supply  
current, lower input bias current, lower propagation  
delay, dedicated ESD protection cells with improved  
negative input voltage handling. The TL331B-Q1 can  
drop-in replace both the TL331-Q1 "I" and "Q"  
versions. The TL391B-Q1 provides an alternate  
pinout of the TL331B-Q1.

This device consists of a single voltage comparator  
designed to operate from a single power supply over  
a wide range of voltages. Operation from dual  
supplies also is possible if the difference between the  
two supplies is 2 V to 36 V and VCC is at least 1.5 V  
more positive than the input common-mode voltage.  
Current drain is independent of the supply voltage. To  
achieve wired-AND relationships, one can connect the  
output to other open-collector outputs.  
0.43 mA Typ (B version)

Low input bias current, 3.5 nA typ (B version)  
Low input offset voltage, 0.37 mV typ (B Version)  
Differential input voltage range equal to maximum-  
rated supply voltage, ±36 V  
Input range includes ground  
TL391B-Q1 provides an alternate pinout  
Output compatible With TTL, MOS and CMOS
