APPLICATION NOTE
With the VBUS54DD-HS4 a double, high speed USB-port or up to 4 other high speed signal or data lines can be protected
against transient voltage signals. Negative transients will be clamped close below the ground level while positive transients will
be clamped close above the working range. The high speed data lines, D₁+, D₂+, D₁- and D₂-, are connected to pin 1, 3, 4, and
5, pin 2 or 6 are connected to ground. As long as the signal voltage on the data lines is between the ground- and the break
down level, the low input capacitance of each channel offers a very high isolation to ground and to the other data lines. But as
soon as any transient signal exceeds this working range, the VBUS054DD-HS4 clamps the transient to ground or to the
avalanche break down voltage level.
