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 1ua over operating temperature range Inputs and outputs can be isolated from system ground High common-mode slew rate SO-14 (Plastic micropackage) DIP14 (Plastic package)

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.
