For device reliability, it is recommended to
follow common printed-circuit board layout guidelines such as follows:
- Bypass capacitors should be used on power supplies and should be placed as close
as possible to the VCCA, VCCB pin, and GND
pin.
- 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 encounters low impedance at the source driver.
