* 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 can drive 50
transmission lines on the incident edge. Each output drives one 50 parallel terminated transmission line to
VTT = VCC/2. Alternately, the device drives up to two 50 series terminated transmission lines per output.
2. IIN current is a result of internal pull–up resistors.
