APPENDIX A
ELECTRICAL CHARACTERISTICS
*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 V
DD
) enhances reliability of
operation.
NOTES:
1. This is an approximate value, neglecting P
I/O
.
2. For most applications P
I/O
P
INT
and can be neglected.
3. K is a constant pertaining to the device. Solve for K with a known T
A
and a measured P
D
(at equilibrium). Use
this value of K to solve for P
D
and T
J
iteratively for any value of T
A
.
