2 ELECTRICAL CHARACTERISTICS
2.1 ABSOLUTE MAXIMUM RATINGS
This product contains devices to protect the inputs
against damage due to high static voltages, how-
ever it is advised to take normal precaution to
avoid application of any voltage higher than maxi-
mum rated voltages.
For proper operation it is recommended that VI
and VO must be higher than VSS and smaller than
VDD. Reliability is enhanced if unused inputs are
connected to an appropriated logic voltage level
(VDD or VSS).
Power Considerations.The average chip-junc-
tion temperature, Tj, in Celsius can be obtained
from:
Tj=
TA + PD x RthJA
Where:TA =
Ambient Temperature.
RthJA = Package thermal resistance
(junction-to ambient).
PD =
Pint + Pport.
Pint =
IDD x VDD (chip internal pow-
er).
Pport = Port power dissipation
(determined by the user).
