7 ELECTRICAL CHARACTERISTICS
7.1 ABSOLUTE MAXIMUM RATINGS
This product contains devices to protect the inputs
against damage due to high static voltages, how-
ever it is advisable to take normal precaution to
avoid application of any voltage higher than the
specified maximum rated voltages.
For proper operation it is recommended that V
I
and V
O
be higher than V
SS
and lower than V
DD
.
Reliability is enhanced if unused inputs are con-
nected to an appropriate logic voltage level (V
DD
or V
SS
).
Power Considerations
.The average chip-junc-
tion temperature, T
J
, in Celsius can be obtained
from:
T
J
=
TA + PD x RthJA
Where: T
A
=
Ambient Temperature.
RthJA = Package thermal resistance
(junction-to ambient).
P
D
=
P
INT
+ P
PORT
.
P
INT
=
I
DD
x V
DD
(chip internal power).
P
PORT
=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.
