High Speed Dual Comparator
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
