*One pin at a time, observing maximum power dissipation limits.
Internal circuitry protects the inputs against damage caused by high static voltages or
electric fields; however, normal precautions are necessary to avoid application of any
voltage higher than maximum-rated voltages to this high-impedance circuit. Extended
operation at the maximum ratings can adversely affect device reliability. Tying unused
inputs to an appropriate logic voltage level (either GND or VDD) enhances reliability of
operation.

NOTES:
1. This is an approximate value, neglecting PI/O.
2. For most applications PI/O « PINT and can be neglected.
3. K is a constant pertaining to the device. Solve for K with a known TA and a measured PD (at equilibrium). Use
this value of K to solve for PD and TJ iteratively for any value of TA.
