TPD12S521DBTRG4

单芯片HDMI发送器端口保护和接口器件 SINGLE-CHIP HDMI TRANSMITTER PORT PROTECTION AND INTERFACE DEVICE

Description

The TPD12S521 is a single-chip electro-static discharge ESD circuit protection device for the high definition multimedia interface HDMI transmitter port. While providing ESD protection with transient voltage suppression TVS diodes, the TVS protection adds little or no additional glitch in the high-speed differential signals. The high-speed transition minimized differential signaling TMDS ESD protection lines add only 0.8-pF capacitance.
