ABSOLUTE MAXIMUM RATINGS*
AS5C512K8
*Stresses greater than those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. This is
Voltage on Vcc Supply Relative to Vss
Vcc ..............................................................................-.5V to +7.0V a stress rating only and functional operation of the device at
Storage Temperature (Plastic)......................-65°C to +150°C these or any other conditions above those indicated in the
Storage Temperature (Ceramic)...................-55°C to +125°C operation section of this specification is not implied. Exposure
Short Circuit Output Current (per I/O)…........................20mA to absolute maximum rating conditions for extended periods
Voltage on any Pin Relative to Vss.................-.5V to Vcc+1V may affect reliability.
Maximum Junction Temperature**..............................+150°C ** Junction temperature depends upon package type, cycle
Power Dissipation ................................................................1W time, loading, ambient temperature and airflow, and humidity.
