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
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Rev. 1.0.3
Features
• Operates From a Single 5V Supply
• Typically 80ns Resp onse 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.

Notes :
1. The offset voltage and offset currents given are the maximum values required to drive the output within a volt of either
supply with a 1mA load. Thus, these parameters define an error band and take into account the worst case effects of
voltage gain and input impedance.
2. The response time specified is for a 100mV input step with 5mV overdrive.
