Absolute Maximum Ratings
VDD referenced to GND ....................................................................................................................................................... 7V
Operating temperature under bias ....................................................................................................................... 0°C to +70°C
Storage temperature ......................................................................................................................................... -40°C to +150°C
Voltage on I/O pins referenced to GND ........................................................................................GND -0.5V to VDD +0.5V
Power dissipation .......................................................................................................................................................... 0.5 Watts
Stresses above those listed underAbsolute 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
the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product
reliability.
