SN65HVD888DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	R	output	Receive data output. CMOS-level digital output driven by the differential receiver comparing bus pins A and B.
2	RE	input	Receiver enable, active low. Drive low to enable the receiver output R; drive high to place R in high-impedance.
3	DE	input	Driver enable, active high. Drive high to enable the differential bus driver onto A/B; drive low to place the driver outputs in high-impedance.
4	D	input	Driver data input. CMOS-level digital input whose state (when DE is asserted) is transmitted differentially onto bus pins A and B.
5	GND	power_in	Local device ground / reference potential.
6	A	bidirectional	RS-485 differential bus I/O pin A (complementary to B). Driver output when DE is high, receiver input when DE is low. Rated ±18 V DC on the bus and ±100 V transient through 100 Ω.
7	B	bidirectional	RS-485 differential bus I/O pin B (complementary to A). Driver output when DE is high, receiver input when DE is low. Rated ±18 V DC on the bus and ±100 V transient through 100 Ω.
8	VCC	power_in	Supply voltage input, 4.5 V to 5.5 V (5 V nominal). Bypass with a local decoupling capacitor to GND.
