LTC1480CS8#TRPBF from Analog Devices, in a SO-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, three-state: HIGH if A > B by 200mV and RE is LOW, LOW if A < B by 200mV, high impedance when RE is HIGH.
2	RE	input	Receiver output enable: LOW enables RO, HIGH forces RO into high impedance; RE HIGH with DE LOW enters 1µA shutdown.
3	DE	input	Driver output enable: HIGH enables driver outputs A and B, LOW forces them high impedance; with RE HIGH the part enters low power (1µA) shutdown.
4	DI	input	Driver input: with DE HIGH, a low forces A LOW and B HIGH, a high forces A HIGH and B LOW.
5	GND	power_in	Ground.
6	A	bidirectional	Driver output/receiver input (A), common mode range -7V to 12V.
7	B	bidirectional	Driver output/receiver input (B), common mode range -7V to 12V.
8	VCC	power_in	Positive supply, 3.0V < VCC < 3.6V.
