Table 2. Absolute Maximum Ratings(1)
1. Absolute maximum continuous ratings are those maximum 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.

2. The MPC941 is capable of driving 50
transmission lines on the incident edge. Each output drives one 50 parallel terminated transmission
line to a termination voltage of VTT. Alternatively, the device drives up to two 50 series terminated transmission lines.
