The is a VGA port protector in 16 pin TQFN package. It integrates level translating buffers and features R, G, B port protection for VGA signals. It has H, V horizontal, vertical translating buffers that take low-level CMOS inputs from graphics outputs to meet full +5V, TTL-compatible outputs. Each output can drive ±10mA and meet the VESA specification. In addition, device takes +5V, direct digital control DDC signals and translates it to lower level required by graphics device. This level is set by user by connecting VL to graphics output supply. The R, G, B terminals protect graphics output pins against electrostatic discharge ESD events. All seven outputs have high-level ESD protection. It is used in notebook computers, desktops, servers and graphics cards.
