8.2.1.1.2 System Level ESD Protection

System-level ESD (per EN61000-4-2) may occur as the result of a cable being plugged in, or a user touching the USB receptacle or cable plug exposed pins. The recommended capacitor on the OUT pin helps reduce the severity of ESD hit on the VBUS path thereby protecting the OUT pin of device. The device has ESD protection built into the CC1 and CC2 pins so that no external protection is necessary as long as proper trace layout guidelines are practiced. Refer to the Layout Guidelines section for external component placement and routing recommendations.
