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 at low level: if A-B >= -50mV, RO outputs a high level; if A-B <= -200mV, RO outputs a low level. High-Z when /RE is high. |+| 2 | /RE | input | Receiver output enable (active-low). When /RE = low, RO output is valid. When /RE = high, RO is in high-impedance state. When /RE = high AND DE = low, the device enters low-power shutdown mode. |+| 3 | DE | input | Driver output enable (active-high). When DE = high, driver output is active. When DE = low, driver outputs are high-impedance. When /RE = high AND DE = low, the device enters low-power shutdown mode. |+| 4 | DI | input | Driver input. When DE = high, a low on DI forces the in-phase output (A) low and the anti-phase output (B) high; a high on DI forces A high and B low. |+| 5 | GND | power_in | Ground reference for the device. |+| 6 | A | bidirectional | RS-485/RS-422 non-inverting bus pin. Receiver in-phase input and driver in-phase output. ±15kV HBM ESD protected. Absolute max ±13V. |+| 7 | B | bidirectional | RS-485/RS-422 inverting bus pin. Receiver inverse-phase input and driver inverse-phase output. ±15kV HBM ESD protected. Absolute max ±13V. |+| 8 | VCC | power_in | Positive supply terminal: 4.5V <= VCC <= 5.5V. Bypass with 0.1µF to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GATEMODE |+| Package | SOP-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `GM75176E`++## CAD (KiCad official)++- Symbol: `GM75176E`+- 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:** [GATEMODE datasheet](docs/gm75176e-datasheet.pdf) (11 pp, sha256 `7fdcabc3b1e36f92`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
