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. The TL331E-Q1 extends the temp range
up to 150ºC, meeting AEC-Q100 Grade 0 temperature requirements.
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 2V to 36V and VCC is at least 1.5V 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.
