11.1 Layout Guidelines

To assure reliability of the device, following common printed-circuit board layout guidelines is recommended.

  • Bypass capacitors should be used on power supplies.
  • Short trace lengths should be used to avoid excessive loading.
  • PCB signal trace-lengths must be kept short enough so that the round-trip delay of any reflection is less than the one shot duration, approximately 30 ns, assuring that any reflection encounters low impedance at the source driver.
  • To help adjust rise and fall times of signals depending on system requirements, place pads on the signal paths for loading capacitors or pullup resistors.
