XL2551

XINLUDA · CAN Transceivers · SOP-8

XL2551 from XINLUDA, 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; TTL-compatible input connected to CAN controller transmitter output, with internal 25 kΩ pull-up to VDD; Low state produces Dominant output, High state produces Recessive output on CANH/CANL.
2 VSS power_in Ground supply pin.
3 VDD power_in Positive supply voltage pin; operating voltage range 4.5V to 5.5V.
4 RXD output Receive Data Output; CMOS-compatible output connected to CAN controller receiver input, High when CAN bus is Recessive and Low in Dominant state.
5 VREF power_in Reference Output Voltage; provides VDD/2 reference voltage.
6 CANL bidirectional CAN Low-Level Voltage I/O; drives low side of CAN differential bus and is tied internally to receive input comparator, voltage range -35V to +35V.
7 CANH bidirectional CAN High-Level Voltage I/O; drives high side of CAN differential bus and is tied internally to receive input comparator, voltage range -35V to +35V.
8 RS input Slope-Control Input; used to select operating mode (High-Speed when VRS < 0.3VDD, Slope-Control when 0.4VDD < VRS < 0.6VDD, Standby when VRS > 0.75VDD) via external biasing resistor.
