Pin Description
PIN NAME FUNCTION
1 TXD
Transmit Data Input. TXD is a CMOS/TTL-compatible input from a CAN controller. TXD has an
internal 75kΩ pullup resistor.
2 GND Ground
3V
CC
Supply Voltage. Bypass V
CC
to GND with a 0.1µF capacitor.
4 RXD Receive Data Output. RXD is a CMOS/TTL-compatible output.
5 SHDN
Shutdown Input, CMOS/TTL-Compatible. Drive SHDN high to put the MAX3051 in shutdown.
SHDN has an internal 75kΩ pulldown resistor to GND.
6 CANL CAN Bus Line Low
7 CANH CAN Bus Line High
8RS
Mode-Select Input. Drive RS low or connect to GND for high-speed operation. Connect a resistor
between RS and GND to control output slope. Drive RS high to put into standby mode (see the
Mode Selection section).
