NOTES:

1. Stresses above 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 operation section of this specification is not

implied.

2. For operating at elevated temperatures, the device must be derated based on +150

°C maximum junction temperature and thermal

resistance of 40

°C/W for plastic DIP and 42°C/W for PLCC.

3. This product includes circuitry specifically designed for the protection of its internal devices from damaging effects of excessive static

charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying any voltages larger than the rated maxima.

NOTES:

1. Parameters are valid over specified temperature and voltage range.

2. These values were not explicitly tested; they are guaranteed by design and characterization data.

3. X1/CLK and X2 are not tested with a crystal installed.

4. This specification applies to revision D, revision E and later revisions.
