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 | RO | output | Receiver Output. When /RE is low: RO = high if (A − B) ≥ −10 mV, RO = low if (A − B) ≤ −200 mV. High-impedance when /RE is high. |+| 2 | /RE | input | Receiver Output Enable (active-low). Drive /RE low to enable RO; RO is high impedance when /RE is high. Driving /RE high with DE low enters low-power shutdown mode. |+| 3 | DE | input | Driver Output Enable (active-high). Drive DE high to enable A/B driver outputs; outputs are high impedance when DE is low. /RE high with DE low enters low-power shutdown mode. |+| 4 | DI | input | Driver Input. With DE high, a low on DI forces the non-inverting output (A) low and inverting output (B) high; a high on DI forces A high and B low. VIH ≥ 2.0 V, VIL ≤ 0.8 V. |+| 5 | GND | power_in | Ground reference for all voltages. Exposed metal pad on the back of DFN3×3-8 and MSOP/VSSOP-8 packages is recommended to be connected to GND. |+| 6 | A | bidirectional | Non-inverting Receiver Input and non-inverting Driver Output on the RS-485/RS-422 bus. Tolerates −15V to +15V bus fault, ±15 kV HBM ESD. Receiver input resistance ≥ 12 kΩ. |+| 7 | B | bidirectional | Inverting Receiver Input and Inverting Driver Output on the RS-485/RS-422 bus. Tolerates −15V to +15V bus fault, ±15 kV HBM ESD. Receiver input resistance ≥ 12 kΩ. |+| 8 | VCC | power_in | Positive supply. 3.0 V to 5.5 V operating range; +7 V absolute maximum. Decouple to GND with a local bypass capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SIT |+| Package | SOP-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `SIT65HVD75DR`+- `SIT65HVD75DRC`++## CAD (KiCad official)++- Symbol: `SIT65HVD75DR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [SIT datasheet](docs/sit65hvd75dr-datasheet.pdf) (21 pp, sha256 `35221d50c73eaa44`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
