LM119/LM219/LM319
High Speed Dual Comparator
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, DTLand TTLas 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 cur-
rent, and voltage gain.
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 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.

Note 3: For supply voltages less than ±15V the absolute maximum input voltage is equal to the supply voltage.
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
packages is 100˚C/W, junction to ambient.
Note 5: These specifications apply for VS=±15V, and the Ground pin at ground, and −55˚C ≤TA≤+125˚C, unless otherwise stated. With the LM219, however, all
temperature specifications are limited to −25˚C ≤TA≤+85˚C. The offset voltage, offset current and bias current specifications apply for any supply voltage from a
single 5V supply up to ±15V supplies. Do not operate the device with more than 16V from ground to VS.
Note 6: The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply witha1mAload. Thus, these
parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
Note 7: The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.
Note 8: Output is pulled up to 15V through a 1.4 kΩresistor.
Note 9: Refer to RETS119X for LM119H/883 and LM119J/883 specifications.

Note 10: For supply voltages less than ±15 the absolute maximum input voltage is equal to the supply voltage.
Note 11: The maximum junction temperature of the LM319A and LM319 is 85˚C. For operating at elevated temperatures, devices in the H10 package must be de-
rated based on a thermal resistance of 160˚C/W, junction to ambient, or 19˚C/W, junction to case. The thermal resistance of the N14 and J14 package is 100˚C/W,
junction to ambient. The thermal resistance of the M14 package is 115˚C/W, junction to ambient.
Note 12: These specifications apply for VS=±15V, and 0˚C ≤TA≤70˚C, unless otherwise stated. The offset voltage, offset current and bias current specifications
apply for any supply voltage from a single 5V supply up to ±15V supplies. Do not operate the device with more than 16V from ground to VS.
