SP1486EEN-L from MaxLinear, 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: high when RE is low and (A-B) >= -40mV, low when (A-B) <= -200mV, and high impedance when RE is high.
2	RE	input	Receiver output enable, active low; RO is high impedance when RE is high, and driving RE high with DE low enters shutdown; hot-swap input.
3	DE	input	Driver output enable; outputs are enabled when DE is high and high impedance when low, and driving DE low with RE high enters shutdown; hot-swap input.
4	DI	input	Driver input; with DE high, a low on DI forces the non-inverting output low and inverting output high, and a high does the opposite.
5	GND	power_in	Ground.
6	A	bidirectional	Non-inverting receiver input and non-inverting driver output, rated -7V to +12V input range and ±15kV ESD protected.
7	B	bidirectional	Inverting receiver input and inverting driver output, rated -7V to +12V input range and ±15kV ESD protected.
8	VCC	power_in	Positive supply, 4.5V to 5.5V (5V typical); bypass to GND with a 0.1uF capacitor.
