Overview
RailClamps® are low capacitance TVS arrays designed to protect high speed data interfaces. RClamp®0554T has a typical capacitance of only 0.28pF between I/O pins. They may be used to meet the ESD immunity requirements of IEC 61000-4-2. Each device is designed to protect four lines (two differential pairs).
