GM75176E 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 /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.

CAD (KiCad official)

Symbol: GM75176E
Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
3D model: SOP-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gm75176e.step`	122 KB	You want the bare part, or you mark your own boards.
`gm75176e-etched.step`	1.5 MB	You want the part with `GM75176E` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 394 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.
