SL82C250T from Slkor SLKORMICRO Elec, 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	TXD	input	Transmit data input from the CAN controller. Logic LOW drives the bus dominant (CANH high, CANL low); logic HIGH or open leaves the bus recessive. Internal pull-up ensures a recessive state when floating; VIH ≥ 2 V, VIL ≤ 0.8 V.
2	GND	power_in	Ground / 0 V reference for supply and signals.
3	VCC	power_in	Supply voltage input, 4.5 V to 5.5 V (nominal 5 V). Absolute maximum -0.3 to +7 V. Standby supply current is under ~12 μA.
4	RXD	output	Receive data output to the CAN controller. Reports bus state: LOW when the bus is dominant (VID ≥ 0.9 V), HIGH when recessive (VID ≤ 0.5 V). VOH ≥ 4 V at IO = -2 mA, VOL ≤ 0.4 V at IO = 2 mA.
5	VREF	output	Reference voltage output, nominally 0.5 × VCC (typically 2.5 V). Provides a stable mid-supply reference for the CAN controller or external circuitry.
6	CANL	bidirectional	Low-level CAN bus line. Driven low (~1.5 V typ) in dominant state and pulled to 0.5·VCC in recessive state. Withstands -8 V to +18 V DC and ±200 V transient; ±8 kV HBM ESD on the bus pins.
7	CANH	bidirectional	High-level CAN bus line. Driven high (~3.4 V typ) in dominant state and pulled to 0.5·VCC in recessive state. Withstands -8 V to +18 V DC and ±200 V transient; ±8 kV HBM ESD on the bus pins.
8	Rs	input	Slope/standby mode control input. Tie LOW for high-speed mode (driver active); tie HIGH or leave open to force low-current standby mode (ICC < ~5 μA typ, RXD still reports bus wake-up). A resistor to GND sets the driver slope/slew for reduced EMI.
