DescriptionThe TPD7S019 deviceis an integrated electrostatic
discharge (ESD) circuit protection solution for VGA
and DVI-I connectors.It integrates transient voltage
suppression (TVS) protection diodes for VIDEO, DDC
and SYNC signals and meets the IEC61000-4-2
standard for ±8-kV contact ESD protection. The TVS
diodes only add low capacitancesto help signals run high-speed.It also provides level-shifting for the
DDC signals saving external level-shifters. Two
noninverting drivers on HSYNC and VSYNC convert
TTL input levelsto CMOS output levels and each
buffer hasa series termination resistor connectedto
the SYNC_OUT pin, eliminating the external
termination resistors. Three supply lines control the
power railsof the VIDEO, DDC and SYNC channels facilitate interfacing with low voltage video
controller ICsin mixed supply-voltage environments.
The TPD7S019 comes with two package options. The
16-pin RSVis compact and space-saving. The 16-pin
DBQ package and pinout are optimized for easy
board layout.
This ESD protection productisa good solutionto
protect the VGA and DVI-I ports for desktop and
laptop PCs, set top boxes, TVs and monitors.
