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-, 55-, or 15- series termination resistor option to match different transmisison 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.
