The TL331B and TL391B devices are the next generation versions of the industry-standard TL331 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, wider temperature range and improved 2kV ESD performance with drop-in replacement convenience. The TL331B is a drop-in improved replacement for both the TL331I and TL331K versions, while the TL391B provides an alternate pinout of the TL331B to replace competitive devices.

Operation from dual supplies also is possible as long as the difference between the two supplies is within 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. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
