The device uses an advanced clamping structure showing a negative dynamic resistance.
This snap-back behavior strongly reduces the clamping voltage to the system behind the
ESD protection during an ESD event. Do not connect unlimited DC current sources to the
data lines to avoid keeping the ESD protection device in snap-back state after exceeding
breakdown voltage (due to an ESD pulse for instance).
