The device is designed to provide high-level ESD protection for high-speed serial data buses such

as USB, HDMI, DisplayPort, eSATA and LVDS data lines.

Fig. 9. Application diagram

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).

Note: When designing the PCB, give careful consideration to impedance matching and signal

coupling. Do not connect the signal lines to unlimited current sources like, for example, a battery.

Definitions

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.
