DESCRIPTION
This is an isolated supply input for the SYNC_1 and SYNC_2 level shifters and their associ-
ated ESD protection circuits.
This is a supply pin specifically for the VIDEO_1, VIDEO_2 and VIDEO_3 ESD protection cir-
cuits.
Video signal ESD protection channel. This pin is typically tied one of the video lines between
the VGA controller device and the video connector.
Video signal ESD protection channel. This pin is typically tied one of the video lines between

Video signal ESD protection channel. This pin is typically tied one of the video lines between
the VGA controller device and the video connector.
Ground reference supply pin.
This is an isolated supply input for the DDC_1 and DDC_2 level-shifting N-FET gates.
This input is used to connect an external 0.2uF bypass capacitor to the DDC circuits, resulting
in an increased ESD withstand voltage rating for these circuits (±8kV with vs.
±4kV
without).
DDC signal output. Connects to the video connector side of one of the sync lines.
DDC signal input. Connects to the VGA controller side of one of the sync lines.
