8.4.1 Layout Guidelines

It is recommended to follow common printed-circuit board layout guidelines for device reliability, such as the follows:

  • Use bypass capacitors on the power supplies.
  • Use short trace lengths to avoid excessive loading.
  • Place pads on the signal paths for loading capacitors or pullup resistors to help adjust rise and fall times of signals depending on the system requirements.
