* Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or condi-
tions beyond those indicated may adversely affect device reliability. Functional operation under absolute–maximum–rated conditions is not im-
plied.
THERMAL CHARACTERISTICS
Proper thermal management is critical for reliable system operation. This is especially true for high fanout and high drive capa-
bility products. Generic thermal information is available for the Motorola Clock Driver products. The means of calculating die
power, the corresponding die temperature and the relationship to longterm reliability is addressed in the Motorola application
note AN1545.
