LM319: Dual Comparator

The LM319 is a dual high speed voltage comparator designed to operate from a single + 5 V supply up to ±15 V dual supplies. Open collector of the output stage makes the LM319 compatible with RTL, DTL and TTL as well as capable of driving lamps and relays at currents up to 25 mA. Typical response time of 80 ns with ±15 V power supplies makes the LM319 ideal for application in fast A/D converts, level shifters, oscillators, and multivibrators.

Features
