6 ELECTRICAL CHARACTERISTICS
6.1 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 V
SS
and smaller than
V
. Reliability is enhanced if unused inputs are
connected to an appropriated logic voltage level
(V
DD
or V
SS
).
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 V
DD
(chip internal pow-
er).
Pport = Port power dissipation
(determined by the user).
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 at these conditions is not implied. Exposure to maximum rating conditions for extended periods may
affect device reliability.
