  1. 2009/05/15 IP4281CZ10 - ESD protection for high-speed interfaces
General description
The IP4281CZ10 is designed for HDMI interface protection. 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.

Features
*Pb-free, RoHS compliant and free of Halogen and Antimony (dark green compliant)
*ESD protection for HDMI and other LVDS data lines
*All TMDS lines with integrated rail-to-rail clamping diodes for downstream ESD protection of ±8 kV according to IEC61000-4-2, level 4
*Matched 0.5 mm trace spacing
*TMDS lines with £ 0.05 pF matching capacitance between TMDS pairs
*Line capacitance of only 0.7 pF for each channel
*4-channel, 10-terminal Ultra-Thin Leadless Package (UTLP)
*HDMI 1.3a compliant

Applications
The IP4281CZ10 is designed for HDMI receiver and transmitter port protection:
*TV, monitor
*Notebook, main board graphics card and ports
*Set-top box and game consoles
*DVD recorder and player
