SIT3051ESA 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). LOW drives the bus dominant; HIGH leaves the bus recessive. Internally pulled up to VCC.
2	GND	power_in	Ground reference for the device. All voltages are referenced to this pin.
3	VCC	power_in	Transceiver supply voltage, 3.3V nominal (3.0V to 3.6V range). Absolute max -0.3V to +6V.
4	R	output	CAN receive data output (RXD / driver output). LOW for dominant bus state, HIGH for recessive. Output current limits ±11 mA.
5	SHDN	input	Shutdown input, CMOS/TTL compatible. Drive HIGH to enter low-current off mode; internal pull-down to GND keeps the device active if left open. VIH ≥ 2V, VIL ≤ 0.8V.
6	CANL	bidirectional	Low-level CAN bus line. Differential bus I/O with common-mode range -7V to +12V and >±12kV HBM ESD protection. Absolute max -36V to +36V; transient ±100V.
7	CANH	bidirectional	High-level CAN bus line. Differential bus I/O with common-mode range -7V to +12V and >±12kV HBM ESD protection. Absolute max -36V to +36V; transient ±100V.
8	RS	input	Mode select pin. Strong pull-down to GND (<0.33 VCC) selects high-speed mode; strong pull-up to VCC (>0.75 VCC) selects low-power/standby mode; a 10 kΩ to 100 kΩ pull-down to GND selects slope-control mode with adjustable driver transition times.
