DESCRIPTION
PIN CONNECTIONS (top view)
These devices consist of two independent preci-
sion voltage comparators, designed to operate
with single or dual supplies.

1.
2.
3.
All voltage values, except differential voltage, are with respect to network ground terminal.
Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
The magnitude of the input and the output voltages must never exceed the magnitude of the possitive supply voltage.
4. Guaranteed by design.
5.
6.
Short circuit from outputs to Vcc+ can cause excessive heating and eventual destruction.
Pd is calculated with T
= +25°C, T = +150°C and R
= 100°C/W for DIP8 package
= 175°C/W for SO8 package
