For reliability of the device, the following common printed-circuit board layout guidelines are recommended:
- 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.
- Keep Ax and Bx lengths close to prevent skewing the signals.
- 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 < 20 ns. Making sure that any reflection
encounters low impedance at the source driver.
