Pin Functions

PINI/ODESCRIPTION
NAMENO.
TXD 1 Logic Input CAN transmit data input (LOW for dominant and HIGH for recessive bus states)
GND 2 Ground Ground connection
VCC 3 Power 5 V ±10% supply voltage
RXD 4 Logic Output CAN receive data output (LOW for dominant and HIGH for recessive bus states)
VIO 5 Power Transceiver I/O level shifting supply voltage
CANL 6 Bus I/O Low level CAN bus input/output line
CANH 7 Bus I/O High level CAN bus input/output line
SW 8 Logic Input Polarity switch pin. Set to low for normal polarity (default), and high to reverse the polarity of the CAN pins
