GENERAL DESCRIPTION
The AS111 is a voltage comparator that has input currents
nearly a thousand times lower than other similar devices. 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
outputs 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.

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 175°C. For operating at elevated temperatures, devices in the TO08 package
must be derated based on a thermal resistance of 160°C/W, junction to ambient, or 50°C/W, junction to case. The thermal resistance of the
C008 dual-in-line package is 130°C/W, junction to ambient, and 20°C/W Junction to Case. The thermal resistance of the CP10 Cerpack
Flatpak & the GW10 Cerpack Gullwing are 230°C/W for juntion to ambient and 25°C/W Junction to Case.
These figures are based on Still Air
& 1/2 Watt power dissipation.
