VGA7S019
Preliminary
7-CHANNEL INTEGRATED ESD SOLUTION FOR VGA PORT WITH INTEGRATED LEVEL SHIFTER AND MATCHING IMPEDANCE
TVS DIODE
DESCRIPTION
The UTC VGA7S019 is an ESD solution for the VGA or DVI-I port connector. This device integrates ESD protection for all signals, level shifting for the DDC signals and buffering for the SYNC signals. ESD protection for the VIDEO, DDC and SYNC lines is implemented with low-capacitance current steering diodes.
Separate positive supply rails are provided for the VIDEO, DDC and SYNC channels to facilitate interfacing with low voltage video controller ICs to provide design flexibility in multi-supply-voltage environments.
