Supply Voltage. Bypass V
Receive Data Output. RXD is a CMOS/TTL-compatible output from the physical bus lines CANH and CANL.
Shutdown Input. Drive SHDN low to put into shutdown mode (MAX3057). Place a capacitor from SHDN to
ground to utilize the AutoShutdown feature of MAX3050. See the Shutdown and AutoShutdown sections for a
full explanation of SHDN behavior.
CAN Bus Line Low. CANL is fault protected to ±80V.
CAN Bus Line High. CANH is fault protected to ±80V.
Mode Select Pin. Drive RS low or connect to GND for high-speed operation. Connect a resistor from RS to
GND to control output slope. Drive RS high to put into standby mode. See the Mode Selection section.
