6.1 Overview

The TL331 family is a single comparator with the ability to operate up to 36V on the supply pin. This standard device has proven ubiquity and versatility across a wide range of applications. This is due to its very wide supply voltages range (2V to 36V), low Iq, and fast response.

The open-collector output allows the user to configure the output's logic low voltage (VOL) and can be utilized to enable the comparator to be used in AND functionality.

The TL331B and TL391B are performance upgrades to standard TL331 using the latest process technologies allowing for lower offset voltages, lower input bias and supply currents and faster response time over an extended temperature range. The TL331B can drop-in replace the "I" or "K" versions of TL331. The TL391B is an alternate pinout for replacing competitive devices.
