To ensure reliability of the device, the following
common printed-circuit board layout guidelines is 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.
- 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 10ns, ensuring that any reflection encounters low
impedance at the source driver.
