RS485

GR · RS-485 / RS-422 ICs · SOP-8

RS485 from GR, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RO output Receiver output: goes high when VA is more than 200 mV above VB and low when VA is more than 200 mV below VB.
2 RE input Receiver output enable, active low: when driven high, the receiver output RO is placed in high-impedance state.
3 DE input Driver output enable, active high: when DE is low the driver outputs A and B are high-impedance, and DE high puts the chip in transmit mode.
4 DI input Driver input: DI low drives A high and B low, and DI high drives the opposite states.
5 GND power_in Ground, negative supply terminal.
6 A bidirectional Receiver non-inverting input and driver non-inverting output.
7 B bidirectional Receiver inverting input and driver inverting output.
8 VCC power_in Positive supply terminal, 5 V single supply (absolute maximum 10 V).

CAD (KiCad official)

  • Symbol: RS485
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: rs485-etched.step / rs485-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rs485.step / rs485.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: GR datasheet (6 pp, sha256 cfd2c52103050b1e, retrieved 2026-10-09, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
