ISL3152EIBZ-T from RENESAS, 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	RO	output	Receiver output. RO is high when A-B ≥ -50mV; RO is low when A-B ≤ -200mV. RO = high if A and B are unconnected (floating) or shorted (full fail-safe). High-Z when /RE is high.
2	/RE	input	Receiver output enable (active low). RO is enabled when /RE is low; RO is high impedance when /RE is high. Driving /RE=1 with DE=0 puts the device in shutdown mode.
3	DE	input	Driver output enable (active high). Driver outputs Y and Z (internally to A/Y and B/Z on this half-duplex part) are enabled by bringing DE high; they are high impedance when DE is low.
4	DI	input	Driver input. A low on DI forces output Y (A/Y) low and output Z (B/Z) high; a high on DI forces output Y high and output Z low. Has 100mV typical input hysteresis.
5	GND	power_in	Ground connection (0V reference).
6	A/Y	bidirectional	±16.5kV IEC61000 ESD protected RS-485/RS-422 non-inverting receiver input and non-inverting driver output. Pin is an input when DE=0; pin is an output when DE=1. -7V to +12V common-mode input range.
7	B/Z	bidirectional	±16.5kV IEC61000 ESD protected RS-485/RS-422 inverting receiver input and inverting driver output. Pin is an input when DE=0; pin is an output when DE=1. -7V to +12V common-mode input range.
8	VCC	power_in	System power supply input (4.5V to 5.5V, nominal 5V). Bypass with 0.1µF ceramic to GND.
