STMicroelectronics 

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 voltages down 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 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.
