LM119/LM219/LM319

High Speed Dual Comparator

n Operates from a single 5V supply

General Description

n Typically 80 ns response time at 15V

n Minimum fan-out of 2 each side

The LM119 series are precision high speed dual compara-

tors fabricated on a single monolithic chip. They are de-

signed 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.

n Maximum input current of 1 µA over temperature

n Inputs and outputs can be isolated from system ground

n High common mode slew rate

Although designed primarily for applications requiring opera-

tion from digital logic supplies, the LM119 series are fully

specified for power supplies up to 15V. It features faster re-

sponse than the LM111 at the expense of higher power dis-

sipation. However, the high speed, wide operating voltage

range and low package count make the LM119 much more

versatile than older devices like the LM711.

The LM319A offers improved precision over the standard

LM319, with tighter tolerances on offset voltage, offset cur-

rent, and voltage gain.

The LM119 is specified from −55˚C to +125˚C, the LM219 is

specified from −25˚C to +85˚C, and the LM319A and LM319

are specified from 0˚C to +70˚C.

Features

n Two independent comparators
