• Ultra-Low Matching Capacitance: Excellent matching between differential signal pairs (0.05-pF line-line capacitance for the TPD4S009DRY) to minimize inter-pair and intra-pair skew.
• IEC 61000-4-2 Level 4 ESD Protection: Provides ±8-kV contact discharge ESD protection and ±9-kV air discharge protection.
• IEC 61000-4-5 Surge Protection: Withstands surge events up to 2.5 A and 25 W (8/20 µs waveform).
• Low Leakage Current: Typical leakage current of 10 nA with an IO bias of 3.3 V and VCC bias of 5 V.
• Ioff Feature: The TPD4S009 offers an optional VCC supply pin to handle live signals at the D+, D- pins when the VCC pin is connected to zero volts.
• Industrial Temperature Range: Operates over a temperature range of –40°C to 85°C.
• Flow-Through Board Layout: Reduces signal glitches due to routing mismatches between the D+ and D- signal pairs.

• High-Definition Multimedia Interface (HDMI): Protects HDMI 1.4 interfaces with data rates up to 3.4 Gbps.
• Low-Voltage Differential Signaling (LVDS): Suitable for LVDS applications requiring high-speed data transmission.
• Serial Advanced Technology Attachment (SATA): Protects SATA interfaces from ESD and surge events.
• Ethernet and 1394 (FireWire): Applicable to various high-speed Ethernet and FireWire interfaces.
• Set-Top Boxes, DTVs, and Laptop/Desktop Systems: Provides ESD protection for high-speed data lines in consumer electronics.
• Electronic Point of Sale (EPOS) Devices: Ensures reliable operation in EPOS systems by protecting against ESD and surges.
