Recommended Operating
Conditions
The forward voltage should be effective at the current levels needed by the processor,
approximately 2-3 amps. That is, do not use diodes with only a nominal VF which drops
too low at high current.

Note: The recommended and tested operating conditions. Proper device operation outside of
these conditions is not guaranteed.
This device contains circuitry to protect against damage due to high static voltage or
electrical fields. However, it is advised that normal precautions be taken to avoid appli-
cation of any voltages higher than maximum-rated voltages to this high-impedance
circuit. Operational reliability is enhanced if unused inputs are tied to an appropriate
logic voltage level (either GND or VCC).
