LM119-LM219-LM319
High speed dual comparators
DIP14
(Plastic package)
Description
These products are precision high speed dual comparators designed to operate over a wide range of supply voltages do wn to a single 5V logic supply and ground. They feature low input currents and high gains.
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 f or po wer supplies up to ±15V.
They feat ure faster response than LM111 at the expense of higher current consumption. Howe v er, the high speed, wide operating v oltag e ran ge and low package count make the LM119/219/319 much more versatile.

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.
