GM13487E

GATEMODE · RS-485/RS-422 ICs · SOP-8

GM13487E from GATEMODE, in a SOP-8. 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 the receiver is enabled and V(A)-V(B) > -50mV, RO is high; when V(A)-V(B) < -200mV, RO is low. High-impedance when the receiver is disabled.
2 /RE input Active-low Receiver Output Enable. Drive /RE low to enable RO; drive /RE high to let the AutoDirection circuit control the receiver. /RE is a hot-swap input with internal pull-up circuitry during power-up.
3 /SHDN input Active-low Shutdown. Drive /SHDN high for normal operation; drive /SHDN low to put the part in shutdown (typ. 2µA, max 10µA supply current).
4 DI input Driver Input. Drive DI low to force noninverting output (A) low and inverting output (B) high; drive DI high to force A high and B low. DI feeds the internal AutoDirection state machine and is a hot-swap input. Must be driven high to enter the idle state.
5 GND power_in Ground reference for the device.
6 A bidirectional Noninverting Receiver Input and Noninverting Driver Output. Connects to the RS-485/RS-422 differential bus 'A' line. ±15kV HBM/Air-Gap ESD protection; input range −7V to +12V common-mode.
7 B bidirectional Inverting Receiver Input and Inverting Driver Output. Connects to the RS-485/RS-422 differential bus 'B' line. ±15kV HBM/Air-Gap ESD protection; input range −7V to +12V common-mode.
8 VCC power_in Positive Supply, VCC = +3.3V ±5% or +5V ±5%. Bypass VCC to GND with a 0.1µF capacitor. Typical ICC = 0.6mA at 5V, 0.47mA at 3.3V (no load).

CAD (KiCad official)

  • Symbol: GM13487E
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: gm13487e-etched.step / gm13487e-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gm13487e.step / gm13487e.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
gm13487e.step 122 KB You want the bare part, or you mark your own boards.
gm13487e-etched.step 1.7 MB You want the part with GM13487E already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 438 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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