* 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. VCMR is the difference from the most positive side of the differential input signal. Normal operation is obtained when the “HIGH” input is within

the VCMR range and the input swing lies within the VPP specification.

2. The MPC950/951 outputs can drive series or parallel terminated 50Ω (or 50Ω to VCC/2) transmission lines on the incident edge (see Applications

Info section).
