ABSOLUTE MAXIMUM RATINGS*

Voltage on Any pin Relative to VSS.... -1V to +7V

Operating Temperature, Ta (ambient).....

………0

°C to +70°C

Storage Temperature (plastic)...... -55

°C to +150°C

*Stresses greater than those listed under "Absolute

Maximum Ratings" may cause permanent damage

to the device. This is a stress rating only and

functional operation of the device at these or any

other conditions above those indicated in the

operational sections of this specification is not

implied. Exposure to absolute maximum rating

conditions

for

extended

periods

may

affect

reliability.
