3 Description
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.
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.
