GENERAL DESCRIPTION
The AS111 is a voltage comparator that has input currents
nearly a thousand times lower than other similar devices like.
It is also designed to operate over a wider range of supply
voltages: from standard ±15V op amp supplies down to the
single 5V supply used for IC logic. Their output is compatible
with RTL, DTL and TTL as well as MOS circuits. Further,
they can drive lamps or relays, switching voltages up to 50V
at currents as high as 50 mA.
Both the inputs and the outputs of the AS111 can be
isolated from system ground, and the output can drive loads
referred to ground, the positive supply or the negative supply.
Offset balancing and strobe capability are provided and out-
puts can be wire OR’ed. Although slower than some devices
(200 ns response time vs 40 ns), this device is also much less
prone to spurious oscillations.

*Stresses greater than those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. This
is a stress rating only and functional operation of the device
at these or any other conditions above those indicated in the
operation section of this specication is not implied. Exposure
to absolute maximum rating conditions for extended periods
may affect reliability.
Note 4: This rating applies for ±15 supplies. The positive input voltage limit is 30V above the negative supply. The negative input voltage limit is equal to
the negative supply voltage or 30V below the positive supply, whichever is less.
Note 5: The maximum junction temperature of the AS111 is 150°C. For operating at elevated temperatures, devices in the TO08 package must be derated
based on a thermal resistance of 165°C/W, junction to ambient, or 20°C/W, junction to case. The thermal resistance of the dual-in-line
package is 110°C/W, junction to ambient.

Note 7: The offset voltages and offset currents given are the maximum values required to drive the output within a volt of
either supply with a 1mA load. Thus, these parameters dene an error band and take into account the worst-case effects of
