The TL331-Q1 is a single comparator with the ability to operate up to 36 V 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 (2 V to 36 V), 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-Q1 and TL391B-Q1 are performance upgrades to industry standard TL331-Q1 using the latest semiconductor process technologies that allows for lower offset voltages, lower input bias and supply currents and faster response times. The TL331B can drop-in replace the "I" or "Q" versions of TL331-Q1. The TL391B-Q1 is an alternate pinout of the TL331B-Q1 for replacing competitive devices.
