LM319 Datasheet – Dual Comparator, DIP 14 – National

Part Number: LM319

Function: High Speed Dual Comparator

Package: SOIC, DIP 14 Pin

Manufacturer: National Semiconductor (Texas Instruments)


LM319 Comparator


The LM319 series are precision high speed dual comparators fabricated on a single monolithic chip. They are designed to operate over a wide range of supply voltages down to a single 5V logic supply and ground. Further, they have higher gain and lower input currents than devices like the LM710. The uncommitted collector of the output stage makes the LM119 compatible with RTL, DTL and TTL as well as capable of driving lamps and relays at currents up to 25 mA. The LM319A offers improved precision over the standard LM319, with tighter tolerances on offset voltage, offset current, and voltage gain.
