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 and have low input currents and high

gains.

The open collector of the output stage makes

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, are

fully specified for power supplies up to

±15V.

They feature faster response than the LM111 at the

expense of higher power dissipation. However, the

high speed, wide operating voltage range and low

package count make the much more versatile.
