LM119/LM219/LM319 High Speed Dual Comparator General Description The LM119 series are precision high speed dual comparators fabricated on a single monolithic chip. They are designed 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 current, and voltage gain. Features n Two independent comparators n Operates from a single 5V supply 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 operation from digital logic supplies, the LM119 series are fully specified for power supplies up to ± 15V. It features faster response than the LM111 at the expense of higher power dissipation. 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: 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 4: 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 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 kΩ resistor.
