Minimum fan-out of two each side
Maximum input current of 1 µA over the
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 5 V
logic supply and ground. They feature low input
currents and high gains.
The open collector of the output stage makes
them compatible with transistor-transistor logic
(TTL) as well as capable of driving lamps and
relays at currents up to 25 mA.
Although designed primarily for applications
requiring operation from digital logic supplies,
these comparators are fully specified for power
supplies up to ±15 V.
They feature faster response times than the
LM111 at the expense of higher current
consumption. However, the high speed, wide
operating voltage range and low package count
make the LM119, LM219, and LM319 much more
versatile.
