SLAS375–JUNE 2003
As with the GND connection, V
DD
should be connected to a positive power-supply plane or trace that is separate
from the connection for digital logic until they are connected at the power-entry point. In addition, a 1 µF to 10 µF
capacitor in parallel with a 0.1 µF bypass capacitor is strongly recommended. In some situations, additional
bypassing may be required, such as a 100 µF electrolytic capacitor or even a Pi filter made up of inductors and
capacitors—all designed to essentially low-pass filter the –5 V supply, removing the high-frequency noise.
