The LM319 is a dual high speed voltage comparator designed to operate from a single + 5V supply up to 15V 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 25mA. Typical response time of 80ns with 15V power supplies makes the LM319 ideal for application in fast A/D converts, level shifters, oscillators, and multivibrators.
