4.1 Design Considerations

  • Figure 6-4 shows the relationship for rise / fall times being directly proportional to the lumped capacitance.
  • Do not exceed the data sheet loading conditions as the rise or fall times will increase, impacting data throughput.
  • Consider any tolerances of any additional RC components, similar to the data sheet recommendations.
