For device reliability, TI recommends following
common printed-circuit board layout guidelines such as follows:
- 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 30ns, causing any reflection to
encounter low impedance at the source driver.
- Placing 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
