Description
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.
