Texas Instruments offers HDMI protection solutions that integrate ESD protection, current limiting, and level translation into a single device. This helps engineers reduce BOM count and conserve PC board space. Popular parts for these applications are: TPD12S521, for HDMI transmit interfaces with a current limit switch, level translation, and ESD protection; TPD13S523 for HDMI transmit interfaces with current limit switch and ESD protection; and TPD12S520 for HDMI receive ports with level translation and ESD protection.
