Texas Instruments
A potential alternative with a slightly faster data rate (250kbps) in the same SOIC-8 package.
SN65HVD3082ED is a low-power, half-duplex RS-485 transceiver from Texas Instruments in a SOIC-8 package. Finding a suitable replacement involves matching the interface, package, and key electrical parameters.
For close matches like THVD1500DR, electrical risk is low. It is high for parts with different data rates or bus loads.
All top candidates share the same SOIC-8 package, but pinout must be confirmed.
The target and top candidates are active parts from the same major manufacturer.
No confirmed direct drop-in replacement exists without datasheet verification. THVD1500DR and SN65HVD82DR are the closest functional matches and may be pin-compatible.
THVD1500DR or SN65HVD82DR are strong candidates with similar or improved specs, but require pinout verification before use.
The main risks are pinout incompatibility and differences in bus loading or data rate which can affect system performance and node count.

| Feature / factor | SN65HVD3082ED | SN65HVD82DR | THVD1500DR | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOIC-8 | SOIC-8 | SOIC-8 | SOIC-8 — Same package and pin count.; THVD1500DR: Same package and pin count. | |
| Interface | RS-485 | RS-485 | RS-485, RS-422 | RS-485 / RS-485, RS-422 — Identical interface type.; THVD1500DR: Candidate supports target protocol. | |
| Data Rate | 200 kbps | 250 kbps | 300 kbps | 250 kbps / 300 kbps — Slightly faster, generally acceptable.; THVD1500DR: Candidate is faster, generally acceptable. | |
| Temperature | -40°C to 85°C | -40°C to 85°C | -40°C to 125°C | -40°C to 85°C / -40°C to 125°C — Identical operating range.; THVD1500DR: Wider operating range. | |
| Voltage | 4.5V to 5.5V | 4.5V to 5.5V | 4.5V to 5.5V | 4.5V to 5.5V — Identical supply voltage range.; THVD1500DR: Identical supply voltage range. |
THVD1500DR and SN65HVD82DR are excellent alternatives, offering similar or better performance in the same package. Pinout and system behavior should be verified.
