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.

General Description

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.

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

n Operates from a single 5V supply

The LM319A offers improved precision over the standard

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

rent, and voltage gain.

n Typically 80 ns response time at 15V

n Minimum fan-out of 2 each side

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-

Note 4: The maximum junction temperature of the LM119 is 150˚C, while that of the LM219 is 110˚C. For operating at elevated temperatures, devices in the H10

package must be derated based on a thermal resistance of 160˚C/W, junction to ambient, or 19˚C/W, junction to case. The thermal resistance of the J14 and N14

Note 6: The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a 1 mA load. Thus, these

parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
