STMicroelectronics LM119-LM219-LM319 High Speed Dual Comparators Datasheet
This document describes the LM119, LM219, and LM319 series of precision high-speed dual comparators. These devices are designed to operate over a wide range of supply voltages down to a single +5V logic supply and ground. They feature low input currents and high gains, with open collector outputs compatible with TTL and capable of driving lamps or relays.
