* 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.

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