Description
These products are precision high speed dual
comparators designed to operate over a wide
range of supply voltages down to a single 5V logic
supply and ground. They feature low input
currents and high gains.
Pin connections

The open collector of the output stage makes it
compatible with TTL as well as capable of driving
lamps and relays at currents up to 25mA.

Although designed primarily for applications
requiring operation from digital logic supplies, the
comparators are fully specified for power supplies
up to ±15V.

They feature faster response than LM111 at the
expense of higher current consumption. However,
the high speed, wide operating voltage range and
low package count make the LM119/219/319
much more versatile.

1. For supply voltages lower than ±15V 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. Rth are typical values.
4. Human body model: 100pF discharged through a 1.5kΩ resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
5. Machine model: a 200pF cap is charged to the specified voltage, then discharged directly between two pins
of the device with no external series resistor (internal resistor < 5Ω), 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 VCC = ±15V, unless otherwise stated.The offset voltage, offset current and bias current
specifications apply for any supply voltage from a single +5V up to ±15V supplies. The offset voltages and offset current
given are the maximum values required to drive the output down to 1V or up to +14V with a 1mA 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, Vo ≈ 1.4V, no load, with VCC from 5V to ±15V and over the full input common-mode range.
3. The response time specified is for a 100mV input step with 5mV overdrive.
