Product Overview
The THVD8000 is a Texas Instruments RS-485 OOK power-line transceiver for Signal_Chain designs using half-duplex bus communication. It operates from a recommended 3 V to 5.5 V supply and supports carrier-frequency selection from 125 kHz to 5 MHz through the F_SET resistor. In modulation mode, the data rate is specified as f0 / 10 bps, with an extracted maximum of up to 500 kbps at f0 / bps = 10.
The device uses A and B bus pins with a -7 V to 12 V operational common-mode range and ±18 V DC fault protection. Bus protection facts include ±16 kV HBM ESD from A and B to GND, ±8 kV IEC contact discharge, ±15 kV IEC air-gap discharge, and ±4 kV IEC 61000-4-4 electrical fast transient protection.
The package is an 8-pin SOT-23 DRL with a 2.90 mm × 1.60 mm body. Thermal data include 106.6 °C/W junction-to-ambient resistance and a 170 °C maximum junction temperature rating. MODE selects receive or transmit operation, while D provides the driver data input.

Procurement Notes
When requesting a quote for THVD8000, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What supply range does the THVD8000 support?
The THVD8000 has a recommended operating supply voltage range of 3 V to 5.5 V. Its absolute maximum VCC rating is -0.5 V to 7 V, based on the extracted datasheet facts.
What carrier frequencies can the THVD8000 use?
