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 short-
circuits on all amplifiers.
3. R
th
are typical values.
4. Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
5. Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two
pins of the device with no external series resistor (internal resistor < 5
Ω),
done for all couples of pin
combinations with other pins floating.
6. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.

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

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.
