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 that reflects the state of the differential receiver comparing bus pins A and B. High-Z when RE is high (receiver disabled). |+| 2 | RE | input | Receiver enable, active low. Drive low to enable the receiver and drive R with the bus state; drive high to place R in high-impedance and (with DE=low) enter low-power standby (typ. 1 µA). |+| 3 | DE | input | Driver enable, active high. Drive high to enable the differential driver so that D is transmitted onto the A/B bus pins; drive low to place the driver outputs in high-impedance. |+| 4 | D | input | Driver data input. CMOS-level TTL-compatible logic input; the state at D sets the differential polarity driven onto A/B when DE is high. VIH ≥ 2 V, VIL ≤ 0.8 V. |+| 5 | GND | power_in | Local device ground / reference potential. Return for the VCC supply and reference for all logic-level I/O. |+| 6 | A | bidirectional | RS-485 differential bus I/O, complementary to B. Acts as the non-inverting driver output when DE=high and as the non-inverting receiver input when the driver is disabled. Fault-protected to ±30 V (per '1787 spec) and rated to ±16 kV IEC HBM. |+| 7 | B | bidirectional | RS-485 differential bus I/O, complementary to A. Acts as the inverting driver output when DE=high and as the inverting receiver input when the driver is disabled. Fault-protected to ±30 V (per '1787 spec). |+| 8 | VCC | power_in | Supply voltage input, 4.5 V to 5.5 V (nom 5 V). Typical ICC is 5 mA in operation and 1 µA in standby (DE=low, RE=high). Bypass locally with a 100 nF ceramic to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOP-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `SN65HVD1787EIM`+- `SN65HVD1787EIM/TR`+- `SN65HVD1787EIMEIN`+- `SN65HVD1787EIMM`+- `SN65HVD1787EIMM/TR`++## CAD (KiCad official)++- Symbol: `SN65HVD1787EIM`+- 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:** [HGSEMI datasheet](docs/sn65hvd1787eim-datasheet.pdf) (25 pp, sha256 `5c40e5bdde3db2e4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
