ST1480ABDR from STMicroelectronics, in a SO-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. If A-B > 200 mV, RO is high; if A-B < -200 mV, RO is low. High-impedance in shutdown (RE high, DE low).
2	~RE	input	Active-low Receiver Output Enable. RO is enabled when RE is low; RO is high impedance when RE is high. If RE is high and DE is low, the device enters low-power shutdown mode.
3	DE	input	Driver Output Enable. Driver outputs A/B are enabled when DE is high and high-impedance when DE is low. If RE is high and DE is low, the device enters low-power shutdown mode.
4	DI	input	Driver input. A low on DI forces bus output A low and B high; a high on DI forces A high and B low (when DE = high).
5	GND	power_in	Ground reference (0 V).
6	A	bidirectional	Non-inverting RS-485/RS-422 bus pin: non-inverting receiver input and non-inverting driver output. ±15 kV HBM ESD protected; withstands -7 V to +12 V common-mode.
7	B	bidirectional	Inverting RS-485/RS-422 bus pin: inverting receiver input and inverting driver output. ±15 kV HBM ESD protected; withstands -7 V to +12 V common-mode.
8	VCC	power_in	Supply voltage: VCC = 3 V to 3.6 V (3.3 V nominal). Absolute maximum 7 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`st1480abdr.step`	123 KB	You want the bare part, or you mark your own boards.
`st1480abdr-etched.step`	2.2 MB	You want the part with `ST1480ABDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 553 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.
