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 output driven from the differential bus receiver comparing A vs. B. |+| 2 | /RE | input | Receiver enable, active low. Internal ~2-MΩ pull-up; drive low to enable the receiver output on R. |+| 3 | DE | input | Driver enable, active high. Internal ~2-MΩ pull-down; drive high to enable the differential bus driver onto A/B. |+| 4 | D | input | Driver data input. Digital input carrying the TX data driven onto the A/B differential bus when DE is high. |+| 5 | GND | power_in | Local device ground reference (0 V). |+| 6 | A | bidirectional | RS-485/RS-422 differential bus I/O, non-inverting (complementary to B). Tolerates -18 V to 18 V absolute-max bus voltage and ±8-kV IEC contact discharge ESD. |+| 7 | B | bidirectional | RS-485/RS-422 differential bus I/O, inverting (complementary to A). Tolerates -18 V to 18 V absolute-max bus voltage and ±8-kV IEC contact discharge ESD. |+| 8 | VCC | power_in | Supply pin, 4.5 V to 5.5 V (5-V nominal). Bypass to GND with a low-ESR ceramic close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `THVD1500DRDR`+- `THVD1500DRD`++## CAD (KiCad official)++- Symbol: `THVD1500DR`+- 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/thvd1500.pdf) (30 pp, sha256 `a98b9643636e84e8`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
