LM119 high-speed dual comparators

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 and have low input

currents and high gains.

Although designed primarily for applications requiring operation from digital logic supplies,

the comparators are fully specified for power supplies up to ±15 V.
