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.

Features

ill Two independent comparators

□ Operates from a single 5V supply

□ Typically 80 ns response time at ±15V

s Minimum fan-out of 2 each side

■ Maximum input current of 1 juA over temperature

■ Inputs and outputs can be isolated from system ground hi 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 ± 1 5V. It features faster response than the LM111 at the expense of higher power dissipation. However, the high speed, wide operating volt

age 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 -2 5 °C to +85°C, and the LM319 is speci

fied from 0°C to + 70°C.

Note 1: For supply voltages less than ± 1 5 V the absolute maximum input voltage is equal to the supply voltage.

Note 2: 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 TO-5 package must be derated based on a thermal resistance of 150°C/W , junction to ambient, or 45°C/W , junction to case. The thermal resistance of the dual-in-line package is 100°C/W, junction to ambient.

Note 3: These specifications apply for Vs = ±1 5 V , and the Ground pin at ground, and - 5 5 ° C ^ TA ^ -M 25°C, unless otherwise stated. With the LM219, however, all temperature specifications are limited to -2 5 ° 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 ± 1 5 V supplies. Do not operate the device with more than 16V from ground to Vs-

Note 4: 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 5: The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.
