Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | R | output | Receive data output (digital). Delivers the received differential bus data as a single-ended CMOS-level signal to the host UART/MCU. |+| 2 | RE | input | Receiver enable, active low. Drive low to enable the receiver output R; drive high to place R in high-impedance. |+| 3 | DE | input | Driver enable, active high. Drive high to enable the differential bus driver on A/B; drive low to place driver outputs in high-impedance. |+| 4 | D | input | Driver data input (digital). CMOS-level TX data from the host UART/MCU that is transmitted as a differential signal on A/B when the driver is enabled. |+| 5 | GND | power_in | Local device ground (reference potential, 0 V). |+| 6 | A | bidirectional | RS-485 differential bus I/O, non-inverting line. Driver output or receiver input, complementary to B. 15-kV ESD protected bus pin. |+| 7 | B | bidirectional | RS-485 differential bus I/O, inverting line. Driver output or receiver input, complementary to A. 15-kV ESD protected bus pin. |+| 8 | VCC | power_in | Positive supply input, 4.5 V to 5.5 V (5-V nominal). Bypass locally with a 100-nF ceramic to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `SN65HVD3082EDRD`+- `SN65HVD3082EDRDR`+- `SN65HVD3082EDRDGK`+- `SN65HVD3082EDRDGKR`+- `SN65HVD3082EDRP`+- `SN65HVD3082EDRNS`+- `SN65HVD3082EDRNSR`++## CAD (KiCad official)++- Symbol: `SN65HVD3082EDR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/sn65hvd3082e.pdf) (40 pp, sha256 `5da24ada598efdc4`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
