LM119-LM219-LM319 is a precision high speed dual comparator designed to operate over a wide range of supply voltages. It features low input currents and high gains. The open collector of the output stage makes it compatible with TTL and capable of driving lamps and relays at currents up to 25mA.
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.
