ABSOLUTE MAXIMUM RATINGS*

Voltage on Vcc Supply Relative to Vss...................-.5V to +7.0V

Storage Temperature ............................................-65

°C to +150°C

Short Circuit Output Current (per I/O)….............................20mA

Voltage on any Pin Relative to Vss......................-.5V to Vcc+1 V

Maximum Junction Temperature**....................................+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 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.
