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.
