MAX3088CSA+T 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: when RE is low and A − B ≥ −50mV, RO is high; when A − B ≤ −200mV, RO is low.
2	RE	input	Receiver output enable: drive RE low to enable RO, which is high impedance when RE is high; RE high with DE low puts the device in low-power shutdown.
3	DE	input	Driver output enable: drive DE high to enable the driver outputs, which are high impedance when DE is low; RE high with DE low enters low-power shutdown.
4	DI	input	Driver input: with DE high, a low on DI forces A low and B high, and a high on DI forces A high and B low.
5	GND	power_in	Ground.
6	A	bidirectional	Noninverting receiver input and noninverting driver output; the driver output and receiver input are rated ±13V (absolute maximum).
7	B	bidirectional	Inverting receiver input and inverting driver output; the driver output and receiver input are rated ±13V (absolute maximum).
8	VCC	power_in	Positive supply; 4.75V ≤ VCC ≤ 5.25V.
