• RESET_B pin was only tested with negative I-test due to product conditioning requirement.
3.4 Voltage and current operating ratings
Absolute maximum ratings are stress ratings only, and functional operation at the
maxima is not guaranteed. Stress beyond the limits specified in the following table may
affect device reliability or cause permanent damage to the device. For functional
operating conditions, refer to the remaining tables in this document.
This device contains circuitry protecting against damage due to high static voltage or
electrical fields; however, it is advised that normal precautions be taken to avoid
application of any voltages higher than maximum-rated voltages to this high-impedance
circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate
logic voltage level (for instance, either V
SS
or V
DD
) or the programmable pullup resistor
associated with the pin is enabled.
