3 Description

The TPD7S019 device is 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 capacitances to help signals run

at 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 levels to CMOS output levels and each

buffer has a series termination resistor connected to

the SYNC_OUT pin, eliminating the external

termination resistors. Three supply lines control the

power rails of the VIDEO, DDC and SYNC channels

to facilitate interfacing with low voltage video

controller ICs in mixed supply-voltage environments.

The TPD7S019 comes with two package options. The

16-pin RSV is compact and space-saving. The 16-pin

DBQ package and pinout are optimized for easy

board layout.

This ESD protection product is a good solution to

protect the VGA and DVI-I ports for desktop and

laptop PCs, set top boxes, TVs and monitors.
