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.
