Product details

Overview

TPD7S019-15DBQR from Texas Instruments is a 7-channel integrated ESD protection IC for VGA and DVI-I ports, providing ±8-kV IEC 61000-4-2 contact ESD protection, 2.5-pF video-line capacitance, integrated 15-Ω SYNC driver output resistance, bidirectional DDC level-shifting FETs, and three isolated supply rails (VCC_VIDEO, VCC_SYNC, VCC_DDC) - deployed at the VGA connector interface in desktop PCs and monitors to safeguard RGB, HSYNC/VSYNC, and DDC_CLK/DAT signals.

For engineers reviewing the TPD7S019-15DBQR datasheet, TPD7S019-15DBQR pinout, TPD7S019-15DBQR application, or TPD7S019-15DBQR equivalent, key selection considerations include its SSOP-16 (DBQ) package flow-through layout, 24-mA SYNC buffer drive capability, 12-ns propagation delay, 9-V VIDEO diode breakdown voltage, and compatibility with 3.3-V/5-V mixed-supply video controller interfaces.

Technical Context

The TPD7S019-15DBQR integrates three functional domains: low-capacitance TVS clamps (2.5 pF typical on VIDEO pins) for high-speed RGB signal integrity; dual noninverting SYNC buffers with integrated 15-Ω series termination resistors driving HSYNC/VSYNC; and bidirectional N-channel FET level-shifters translating DDC_CLK/DDC_DAT between 3.3-V controller and 5-V connector sides.

It operates across –40°C to +85°C with independent 0–5.5-V supplies per domain, enabling robust interfacing in mixed-voltage systems. Its ESD protection architecture triggers only during transients (±8-kV contact), remaining transparent during normal operation with sub-10-µA quiescent current per supply rail.

Pinout & Package

TPD7S019-15DBQR uses a 16-pin SSOP (DBQ) package measuring 4.90 mm × 3.90 mm, optimized for flow-through routing with input and output pins aligned on opposite sides to minimize board trace length between VGA connector and video controller.

Pin/Terminal	Circuit Role	Design Meaning

SYNC_IN1 / SYNC_IN2	SYNC buffer input	TTL-level HSYNC/VSYNC inputs from video controller - referenced to VCC_SYNC.
SYNC_OUT1 / SYNC_OUT2	SYNC buffer output	CMOS-level buffered HSYNC/VSYNC outputs with integrated 15-Ω series resistor - drive VGA connector directly.
DDC_IN1 / DDC_IN2	DDC level-shifter input	Bi-directional I²C signal inputs from controller side - support 3.3-V logic with 5-V pull-ups on cable side.
DDC_OUT1 / DDC_OUT2	DDC level-shifter output	Bi-directional I²C signal outputs to VGA connector - translated to 5-V compatible levels.
VCC_VIDEO / VCC_SYNC / VCC_DDC	Isolated power rail	Independent supplies for VIDEO, SYNC, and DDC domains - enable voltage domain isolation and noise separation.
BYP	Power bypass	Connect 0.2-µF capacitor to GND - improves ESD transient response and stabilizes internal bias networks.

Key Features

Feature	Design Value
7-channel integrated protection	Combines ESD clamping, level-shifting, buffering, and impedance matching in one DBQ package - reduces BOM count by ≥6 discrete components.
Flow-through pin mapping	Input and output pins arranged linearly (e.g., VIDEO1 in, VIDEO1 out adjacent) - enables straight PCB routing from connector to controller with no layer jumps.
Three isolated supply domains	VCC_VIDEO, VCC_SYNC, VCC_DDC allow independent voltage assignment - simplifies interface to mixed-supply video SoCs and FPGAs.
Integrated SYNC termination	15-Ω series resistor embedded in each SYNC buffer output - removes two external 0402 resistors and associated layout area.
Low-leakage DDC power-down	<1 µA leakage when VCC_DDC ≤ 0.4 V - enables true low-power standby mode for DDC bus without signal corruption.

Equivalent & Alternatives

The following parts are listed as comparable options for similar VGA port protection applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPD7S019-15RSVR	UQFN-16 (2.6 mm × 1.8 mm) vs. DBQ's SSOP-16 (4.9 mm × 3.9 mm); identical electrical specs and pinout but smaller footprint.	Preferred for ultra-compact designs where board area is constrained; requires finer-pitch reflow profile due to 0.4-mm pitch.	Select TPD7S019-15RSVR when minimizing PCB area is critical and assembly process supports UQFN handling.
TPD2E001DRPR	Single-channel 2-line ESD array (0.5-pF, ±12-kV IEC); no level-shifting, no SYNC buffering, no multi-rail support.	Suitable only for discrete protection of individual DDC or SYNC lines - cannot replace full 7-channel integration of TPD7S019-15DBQR.	Use TPD2E001DRPR only as supplemental protection on specific lines where TPD7S019-15DBQR coverage is insufficient.

Compared with TPD7S019-15RSVR, the TPD7S019-15DBQR offers easier hand-soldering and visual inspection due to gull-wing leads, while TPD2E001DRPR lacks the integrated functionality needed for complete VGA port protection - making it a partial rather than drop-in alternative.

FAQ

What is the primary function of the TPD7S019-15DBQR in a VGA interface?

The TPD7S019-15DBQR serves as a single-chip VGA port protector, integrating ESD clamps for RGB, HSYNC/VSYNC, and DDC signals; level-shifting FETs for DDC_CLK/DAT; and buffered, terminated SYNC outputs. It replaces multiple discrete protection and interface components while maintaining signal fidelity up to 388 MHz - making it essential for achieving IEC 61000-4-2 Level 4 compliance in TPD7S019-15DBQR-based designs.

Does the TPD7S019-15DBQR require external termination resistors on SYNC lines?

No, the TPD7S019-15DBQR integrates 15-Ω series termination resistors directly into each SYNC buffer output (SYNC_OUT1 and SYNC_OUT2), eliminating the need for external resistors. This feature reduces PCB area, component count, and potential impedance mismatch issues - confirmed in the Electrical Characteristics table (RT = 15 Ω) and Functional Description of the TPD7S019-15DBQR datasheet.

Can the TPD7S019-15DBQR support both 3.3-V and 5-V logic levels on DDC lines?

Yes, the TPD7S019-15DBQR uses bidirectional N-channel FETs to translate DDC signals between 3.3-V controller-side logic and 5-V VGA cable-side pull-up levels. This level-shifting is inherent to the device architecture and requires no external components or direction control - a core capability explicitly documented for the DDC_IN1/DDC_OUT1 and DDC_IN2/DDC_OUT2 channels in the TPD7S019-15DBQR pin functions table.

What is the maximum video signal bandwidth supported by the TPD7S019-15DBQR?

The TPD7S019-15DBQR supports video signal bandwidths up to 388 MHz, validated by its 2.5-pF typical input capacitance on VIDEO pins and 12-ns propagation delay on SYNC paths. This enables full compatibility with UXGA (1600×1200 @ 60 Hz) and higher-resolution analog VGA timings - as specified in the Typical Application section of the TPD7S019-15DBQR datasheet under "VIDEO signals data rate: 24 MHz to 388 MHz".

How does the TPD7S019-15DBQR handle power supply isolation between video, sync, and DDC domains?

The TPD7S019-15DBQR employs three independent supply pins - VCC_VIDEO, VCC_SYNC, and VCC_DDC - allowing each functional domain to operate at its optimal voltage (0–5.5 V). This isolation prevents noise coupling between analog RGB paths, digital sync buffers, and I²C DDC signaling, and is fundamental to the device's architecture as described in the Description and Power Supply Recommendations sections of the TPD7S019-15DBQR datasheet.
