Pin Functions

PIN I/O DESCRIPTION
NAME NO.
CANH 7 I/O High-level CAN bus line
CANL 6 I/O Low-level CAN bus line
D 1 I CAN transmit data input (LOW for dominant and HIGH for recessive bus states), also called TXD, driver input
GND 2 GND Ground connection
R 4 O CAN receive data output (LOW for dominant and HIGH for recessive bus states), also called RXD, receiver output
RS 8 I Mode select pin: strong pulldown to GND = high-speed mode, strong pull up to VCC = low-power mode, 10-kΩ to 100-kΩ pulldown to GND = slope control mode
VCC 3 Supply Transceiver 5-V supply voltage
VREF 5 O Reference output voltage
