Overview
The IP4776CZ38, produced by NXP USA Inc., is a fully integrated HDMI interface component designed for HDMI host-interface protection. This device includes level shifting for the DDC (Display Data Channel) channels, backdrive protection for HDMI, and high-level ESD (Electrostatic Discharge) protection diodes for the TMDS (Transition Minimized Differential Signaling) signal lines. It is particularly useful when the receiver operates at a supply voltage lower than the external devices, protecting the I/Os against overvoltages. The component is housed in a 38-pin TSSOP (Thin Shrink Small Outline Package) lead-free package and is Pb-free and RoHS compliant.
