Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

LM319
Dual Comparator
Features
Description
• 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
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 comptible with RTL, DTL and TTL as well as
capable of rivinlamps and relays at currents up to
25mA. Typil espontime of 80ns with ±15V power
supplmakes e M319 ideal for application in fast A/D
covertlevel shiftier, oscillators, and mutivibrators.
