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 maximum

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 con-

nected 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 xVDD (chip internal power).

Pport = Port power dissipation

(determinated by the user).
