IP4282CZ6
ESD protection for high-speed interfaces
Rev. 01 — 30 March 2009
Product data sheet
1. Product profile
1.1 General description
The IP4282CZ6 is designed to protect high-speed interfaces such as HDMI, DVI and
DisplayPort interfaces. The device includes high-level ElectroStatic Discharge (ESD)
protection diodes for the TMDS signal lines.
All TMDS intra-pairs are protected by a special diode configuration offering a low line
capacitance of only 0.7 pF. These diodes provide protection to downstream components
from ESD voltages up to
±8
kV contact according to IEC 61000-4-2, level 4.
