8 ELECTRICAL CHARACTERISTICS
8.1 ABSOLUTE MAXIMUM RATINGS
This product contains devices for protecting the in-
puts against damage due to high static voltages,
however it is advisable to take normal precautions
to avoid applying any voltage higher than the
specified maximum rated voltages.
For proper operation it is recommended that VI
and VO be higher than VSS and lower than VDD.
Reliability is enhanced if unused inputs are con-
nected to an appropriate logic voltage level (VDD
or VSS).
Power Considerations. The average chip-junc-
tion temperature, TJ, in Celsius can be obtained
from:
Where:
TJ = TA + PD x RthJA
TA = Ambient Temperature.
RthJA =Package thermal resistance
(junction-to ambient).
PD = PINT + PPORT.
PINT = IDD x VDD (chip internal power).
PPORT =Port power dissipation

Note:
Stresses above those listed as “absolute maximum ratings” may cause permanent damage to the device. This is a stress
rating only and functional operation of the device under these conditions is not implied. Exposure to maximum rating con-
ditions for extended periods may affect device reliability.
General Warning:
Directly connecting the RESET and I/O pins to VDD or VSS could damage the device if an unintentional internal reset is
generated or the program counter is corrupted (by an expected change to the I/O configuration). To guarantee safe op-
eration, this connection has to be done through a pull-up or pull-down resistor (10Ktypical).
