11.1 Layout Guidelines

General layout best practices are recommended. It is common to have a dedicated ground plane on an inner layer of the board, and pins that are connected to ground must have a low-impedance path to the ground place in the form of wide polygon pours, and multiple vias.

Bypass and decoupling capacitors are commonly used to control the voltage on the VCC pin, using a larger capacitor to provide additional power in the event of a short power supply glitch (typically 1 μF), and a smaller capacitor (typically 0.1 μF) to filter out high-frequency ripple.
