IP4776CZ38

www.DataSheet4U.com IP4776CZ38 Fully integrated HDMI interface with level shifter, ESD and backdrive protection Rev. 01 — 14 July 2006 Product data sheet 1. General description The IP4776CZ38 is designed for HDMI host-interface protection. The IP4776CZ38 includes level shifting for the DDC channels and backdrive protection for HDMI as well as high-level ESD protection diodes for the TMDS signal lines. The level shifting function is required when the receiver operates at a supply voltage lower than the external devices to protect the I/Os against over voltages. The IP4776CZ38 contains four N-channel MOSFETs to provide this level shifting function. Furthermore, all TMDS intra-pairs are protected by a special diode configuration offering an ultra low line capacitance of 0.7 pF only. These diodes provide protection to downstream components from ESD voltages up to ±8 kV contact according to the IEC 61000-4-2, level 4 standard. 2.
