SIT65HVD233DR from SIT, in a SOP-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	D	input	CAN transmit data input (TXD / driver input). Drives the bus dominant when LOW and recessive when HIGH. CMOS-level input compatible with 3.3V logic.
2	GND	power_in	Device ground reference. All voltages are referenced to this pin.
3	VCC	power_in	Transceiver 3.3V supply voltage. Operating range 3.0 V to 3.6 V; absolute max -0.3 V to +6 V. Decouple locally to GND.
4	R	output	CAN receive data output (RXD / receiver output). LOW for dominant bus state, HIGH for recessive. CMOS output driving the protocol controller's RX input.
5	LBK	input	Loopback mode input pin. When asserted, routes the driver's D input internally to the R output for diagnostic self-test without driving the CAN bus.
6	CANL	bidirectional	Low-level CAN bus line. Differential bus I/O paired with CANH; withstands -36 V to +36 V DC and ±12 kV HBM ESD. Terminate the bus with 120 Ω between CANH and CANL.
7	CANH	bidirectional	High-level CAN bus line. Differential bus I/O paired with CANL; withstands -36 V to +36 V DC and ±12 kV HBM ESD.
8	RS	input	Mode-select pin. Strong pull-down to GND selects high-speed mode; strong pull-up to VCC selects low-power (standby) mode; a 10 kΩ-100 kΩ resistor to GND selects slope-control mode with driver slew rate set by the resistor value.
