Avoid long power supply and ground traces (added
inductance causes unwanted voltage transients). Use
power and ground planes wherever possible. In

addition, it is advisable that low ESR bypass capacitors
(4.7µF or 10µF tantalum) be placed as close to the
driver as possible. The driver should be physically
located as close to the device it is driving as possible to
minimize the length of the output trace.
