ILX3485DT from IKSEMICON, 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. CMOS-level output that reflects the differential bus state (A-B). High when (A-B) > +200 mV, low when < -200 mV.
2	/RE	input	Receiver output enable, active low. When low, RO is enabled; when high, RO is high-impedance.
3	DE	input	Driver output enable, active high. When high, the differential driver outputs A and B are enabled; when low, they are high-impedance.
4	DI	input	Driver input. CMOS-level logic input to be transmitted differentially onto A/B when DE is high.
5	GND	power_in	Ground reference (0 V).
6	A	bidirectional	Non-inverting differential bus I/O. Driver output when DE=H; receiver input when /RE=L. Part of the RS-485 twisted-pair bus.
7	B	bidirectional	Inverting differential bus I/O. Driver output when DE=H; receiver input when /RE=L. Part of the RS-485 twisted-pair bus.
8	VCC	power_in	Supply voltage input, 3.0 V to 3.6 V (3.3 V nominal). Bypass to GND with a 0.1 uF ceramic capacitor close to the pin.
