MAX3486EESA+ from Maxim Integrated, in a SOIC-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 that is high if A > B by 200mV and low if A < B by 200mV, and high impedance when RE is high.
2	RE	input	Receiver output enable: RO is enabled when RE is low and high impedance when RE is high; with RE high and DE low the device enters low-power shutdown.
3	DE	input	Driver output enable: driver outputs are enabled when DE is high and high impedance when DE is low; with RE high and DE low the device enters low-power shutdown.
4	DI	input	Driver input where a low forces output A low and B high, and a high forces A high and B low.
5	GND	power_in	Ground.
6	A	bidirectional	Noninverting receiver input and noninverting driver output, with ±15kV ESD protection.
7	B	bidirectional	Inverting receiver input and inverting driver output, with ±15kV ESD protection.
8	VCC	power_in	Positive supply of 3.0V to 3.6V; do not operate the device with VCC above 3.6V.
