* 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 MPC974 outputs can drive series or parallel terminated 50Ω (or 50Ω to VCC/2) transmission lines on the incident edge (see Applications
Info section).
2. Inputs have either pull–up or pull–down resistors which affect input current.
