ABSOLUTE MAXIMUM RATINGS*

Voltage on Vcc Supply Relative to Vss...............-1V to +7.0V

Voltage Range on Any Pin Relative to Vss.........-1V to +7.0V

Short Circuit Output Current (per I/O)….......................50mA

Power Dissipation.................................................................1W

*Stresses greater than those listed under "Absolute

Maximum Ratings" may cause permanent damage to the

device. This is a stress rating only and functional opera-

tion of the device at these or any other conditions above

those indicated in the operation section of this specifica-

tion is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

** Junction temperature depends upon package type,

cycle time, loading, ambient temperature and airflow.
