* Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions beyond those
indicated may adversely affect device reliability. Functional operation under absolute-maximum-rated conditions is not implied.
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.

Per Output
1. The MPC974 outputs can drive series or parallel terminated 50
(or 50 to VCC/2) transmission lines on the incident edge (see Applications
Info section).
2. Inputs have either pull–up or pull–down resistors which affect input current.
