to 70 C for all packages.
The IL393 consists of two independent precision voltage
comparators with an offset voltage specification as low as 2.0 mV max
for two comparators which were designed specifically to operate from
a single power supply over a wide range of voltages.
Application areas include limit comparators, simple analog to
digital converters; pulse, squarewave and time delay generators; wide
range VCO; MOS clock timers; multivibrators and high voltage digital
logic gates.

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, V

should be constrained to the range

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
). Unused
outputs must be left open.
