LM119, LM219 and LM319 are high speed dual comparators produced by Texas Instruments. They work on a wide range of supply voltages down to a single 5V logic supply and ground, with typical response time of 80ns, input current of 1µA, and can drive lamps and relays at currents up to 25mA.
This document is a technical datasheet for the SGS-THOMSON LM119, LM219, and LM319, which are precision high speed dual N-channel comparators. These devices are designed to operate over a wide range of supply voltages, down to a single +5V logic supply, and feature low input currents and high gains. The open collector output stage allows compatibility with TTL logic and the ability to drive lamps and relays at currents up to 25mA.
