Features

• Operates From a Single 5V Supply

• Typically 80ns Response Time at

±15V

• Open Collector Outputs : up to +35V

• High Output Drive Current : 25mA

• Inputs and Outputs can be Isolated From System Ground

• Minimum Fan-Out of 2 (Each Side)

• Two Independent Comparators

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 shiftier, oscillators, and multivibrators.
