LM319MX General Description

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.



  • Operates from a single 5 V supply
  • Typically 80 ns response time at ±15 V
  • Open collector outputs: up to + 35 V
  • High output drive current: 25 mA
  • Inputs and outputs can be isolated from system ground
  • Minimum fan-out of 2 (each side)
  • Two independent comparators


  • This product is general usage and suitable for many different applications.
