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 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
be higher than V
and lower than V
.
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, Tj, in Celsius can be obtained
from:
Tj=TA + PD x RthJA
Where:TA = Ambient Temperature.
RthJA =Package thermal resistance (junc-
tion-to ambient).
PD = Pint + Pport.
Pint =IDD x VDD (chip internal power).
Pport =Port power dissipation (determined
by the user).
Notes:
-
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.
- (1)Within these limits, clamping diodes are guarantee tobe not conductive. Voltages outside these limits are authorised as long as injection
current is kept within the specification.
