11.1 Layout Guidelines

Place the VDD decoupling capacitor close to the device.

Avoid using long traces for the VDD supply node. The VDD capacitor, along with parasitic inductance from the supply to the capacitor, can form an LC tank and create ringing with peak voltages above the maximum VDD voltage.
