LM319 Datasheet | NXP Semiconductors

Philips Semiconductors Linear Products Product specification Dual voltage parator LM219/319 DESCRIPTION The LM319 series are precision high-speed dual parators fabricated on a single monolithic chip. They are designed to operate over a wide range of supply voltages down to a single 5V logic supply and ground. Further, they have higher gain and lower input currents than devices like the µA710. The unmitted collector of the output stage makes the LM319 patible with RTL, DTL, and TTL as well as capable of driving lamps and relays at currents up to 25m A. Although designed primarily for applications requiring operation from digital logic supplies, the LM319 series are fully specified for power supplies up to ±15V. It Features 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 LM319 much more versatile than older devices like the µA711.
