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.
