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, 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 cur-
rent, and voltage gain.

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 LM119 is specified from -55C to +125C, the LM219 is
specified from -25C to +85C, and the LM319A and LM319
are specified from 0C to +70C.

Note 2: For supply voltages less than
15V the absolute maximum input voltage is equal to the supply voltage.
Note 3: The maximum junction temperature of the LM119 is 150C, while that of the LM219 is 110C. For operating at elevated temperatures, devices in the H10
package must be derated based on a thermal resistance of 160C/W, junction to ambient, or 19C/W, junction to case. The thermal resistance of the J14 and N14
packages is 100C/W, junction to ambient.
Note 4: These specifications apply for V

15V, and the Ground pin at ground, and -55C

temperature specifications are limited to -25C

single 5V supply up to
15V supplies. Do not operate the device with more than 16V from ground to V
S
.
Note 5: 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.
Note 6: The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.
Note 7: Output is pulled up to 15V through a 1.4 k
resistor.
Note 8: Refer to RETS119X for LM119H/883 and LM119J/883 specifications.

Note 10: The maximum junction temperature of the LM319A and LM319 is 85C. For operating at elevated temperatures, devices in the H10 package must be de-
rated based on a thermal resistance of 160C/W, junction to ambient, or 19C/W, junction to case. The thermal resistance of the N14 and J14 package is 100C/W,
junction to ambient. The thermal resistance of the M14 package is 115C/W, junction to ambient.
