Features
• Two independent comparators
• Supply voltage: +5 V to ±15 V
• Typically 80 ns response time at ±15 V
• Minimum fan-out of two each side
• Maximum input current of 1 µA over the operating temperature range
• Inputs and outputs can be isolated from system ground
• High common-mode slew rate
Description
These products are precision high-speed dual comparators designed to operate over a wide range of supply voltages down to a single 5 V logic supply and ground. They feature low input currents and high gains.
The open collector of the output stage makes them compatible with transistor-transistor logic
(TTL) as well as capable of driving lamps and relays at currents up to 25 mA.
Although designed primarily for applications requiring operation from digital logic supplies, these comparators are fully specified for power supplies up to ±15 V.
They feature faster response times than the
LM111 at the expense of higher current consumption. However, the high speed, wide operating voltage range and low package count make the LM119, LM219, and LM319 much more versatile.

1. For supply voltages lower than ±15 V the absolute maximum input voltage is equal to the supply voltage.
2. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuits on all amplifiers.
3. R th

1. These specifications apply for V
CC
= ±15 V, unless otherwise stated.The offset voltage, offset current and bias current specifications apply for any supply voltage from a single +5 V up to ±15 V supplies. The offset voltages and offset current given are the maximum values required to drive the output down to 1V or up to +14 V with a 1 mA load current. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
2. At output switch point, V o
≈ 1.4 V, no load, with V
CC
from 5 V to ±15 V and over the full input common-mode range.
3. The response time specified is for a 100 mV input step with 5 mV overdrive.
