PACVGA201QR

Power Management - Specialized Overview

The PACVGA201QR is an ESD protection diode array manufactured by onsemi, designed specifically as a companion circuit for VGA ports. It provides seven channels of electrostatic discharge protection for all signal lines commonly found in a VGA connector. The device meets IEC-61000-4-2 Level-4 ESD requirements, handling up to 8kV contact discharge. It features very low loading capacitance of 4pF typical on VIDEO lines and includes TTL to CMOS level-translating buffers with power down mode for HSYNC and VSYNC lines. The component utilizes three separate power supplies for design flexibility and is housed in a compact 16-pin QSOP package.
