DESCRIPTION/ORDERING INFORMATION
The TPD7S019 is an integrated 7-channel 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.
Three individual 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.
Two non-inverting drivers provide buffering for the HSYNC and VSYNC signals from the video controller IC
(SYNC1, SYNC2). These buffers accept TTL input levels and convert them to CMOS output levels that swing
between Ground and VCC_SYNC, which is typically 5 V. Additionally, each driver has a series termination
resistor (RT) connected to the SYNC_OUT pin, eliminating the external termination resistors typically required for
the HSYNC and VSYNC lines of the video cable. At the SYNC output the TPD7S019 offers 65-
Ω, 55-Ω, or 15-Ω
series termination resistor option to match different transmission line impedances.
Two N-channel MOSFETs provide the level shifting function required when the DDC controller is operated at a
lower supply voltage than the monitor. The gate terminals for the MOSFETs (VCC_DDC) should be connected to
the supply rail (typically 3.3 V) that supplies power to the transceivers of the DDC controller.
The TPD7S019 confirms the IEC61000-4-2 (Level 4) system level ESD protection and ±15KV HBM ESD
protection. This device is offered in space-saving 16-pin DBQ and 16-pin RSV packages.
The TPD7S019 is characterized for operation over ambient air temperature of –40°C to 85°C.
