LM119, LM219, LM319 are precision high speed dual comparators designed to operate over a wide range of supply voltages down to a single 5V logic supply and ground and have low input currents and high gains. The open collector of the output stage makes it compatible with TTL as well as capable of driving lamps and relays at currents up to 25mA. Although designed primarily for applications requiring operation from digital logic supplies, are fully specified for power supplies up to ±15V. They feature faster response than the LM111 at the expense of higher power dissipation. However, the high speed, wide operating voltage range and low package count make the much more versatile.
The SGS‑Thomson LM119, LM219 and LM319 are high‑speed dual comparators that operate from a single +5 V supply and support supply voltages up to +15 V. They feature a typical 80 ns response time, low input currents and a high common‑mode slew rate, making them suitable for digital logic, lamp and relay driving applications.
