LM119-LM219-LM319

High speed dual comparators

Features

■Two independent comparators

■Supply voltage: +5V to ±15V

■Typically 80ns response time at ±15V

■Minimum fan-out of 2 each side

■Maximum input current of 1µa over 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 v oltages 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 w ell 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 a re fully specified for pow er supplies

up to ±15V.

They feature faster response than LM111 at the

e xpense of highe r current consump tion. How e v er ,

the high speed, wide oper ating v olt age r ange and

low package count mak e 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.

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.

5 Package information

In order to meet environmental requirements, ST offers these devices in ECOPACK®

packages. These packages have a lead-free second level interconnect. The category of

second level interconnect is marked on the package and on the inner box label, in

compliance with JEDEC Standard JESD97. The maximum ratings related to soldering

conditions are also marked on the inner box label. ECOPACK is an ST trademark.
