* 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.

Per Output
1. The MPC946 can drive 50
transmission lines on the incident edge. Each output can drive one 50 parallel terminated transmission line to
the termination voltage of VTT = VCC/2. Alternately, the device drives up to two 50 series terminated transmission lines.
2. IIN current is a result of internal pull–up/pull–down resistors.
