* 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.

Per Output

1. The MPC947 outputs can drive series or parallel terminated 50

Ω (or 50Ω to VCC/2) transmission lines on the incident edge (see Applications

Info section).

2. IIN current is a result of internal pull–up resistors.
