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).
