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. CMOS-level digital output from the differential receiver; drives the host UART RX line. Follows the A-B bus differential state when the receiver is enabled (RE low). |+| 2 | RE | input | Active-low receiver enable. Drive low to enable the receiver output R; drive high to place R in high-impedance (receiver disabled). 5-V-tolerant logic input. |+| 3 | DE | input | Active-high driver enable. Drive high to enable the differential driver onto the A/B bus; drive low to place A and B in high-impedance. 5-V-tolerant logic input. |+| 4 | D | input | Driver data input. CMOS-level logic input that sets the differential polarity on A/B when the driver is enabled (DE high). 5-V-tolerant logic input. |+| 5 | GND | power_in | Local device ground / reference potential for VCC and all logic and bus signals. |+| 6 | A | bidirectional | RS-485 differential bus I/O, complementary to B. Non-inverting driver output when DE is high; non-inverting receiver input when RE is low. Bus voltage range -13 V to +16.5 V (abs max), common-mode -7 V to +12 V. |+| 7 | B | bidirectional | RS-485 differential bus I/O, complementary to A. Inverting driver output when DE is high; inverting receiver input when RE is low. Bus voltage range -13 V to +16.5 V (abs max), common-mode -7 V to +12 V. |+| 8 | VCC | power_in | Supply voltage input. Recommended 3.0-3.6 V (3.3 V nom); abs max 5 V. Bypass locally to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `SN65HVD75DRD`+- `SN65HVD75DR`+- `SN65HVD75DRDGK`+- `SN65HVD75DRDGKR`+- `SN65HVD75DRB`+- `SN65HVD75DRBR`++## CAD (KiCad official)++- Symbol: `SN65HVD75DR`+- 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/sn65hvd75.pdf) (47 pp, sha256 `b46f5803fa8302f9`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
