ISL32603EFUZ-T from RENESAS, in a MSOP-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 if A-B ≥ 200mV, low if A-B ≤ -200mV, and high if A and B are floating; 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; connect to GND if the Rx enable function is not required.
3	DE	input	Driver output enable: driver outputs are enabled by bringing DE high and high impedance when DE is low; connect to VCC if the Tx enable function is not required.
4	DI	input	Driver input: a low on DI forces Y low and Z high, a high on DI forces Y high and Z low.
5	GND	power_in	Ground connection.
6	A/Y	bidirectional	±15kV IEC61000 ESD protected RS-485/422 noninverting receiver input and noninverting driver output; input if DE = 0, output if DE = 1.
7	B/Z	bidirectional	±15kV IEC61000 ESD protected RS-485/422 inverting receiver input and inverting driver output; input if DE = 0, output if DE = 1.
8	VCC	power_in	System power supply input, 1.8V to 3.6V for the ISL32603E.
