NAME

FUNCTION

1

TXD Transmit Data Input. TXD is a CMOS/TTL-compatible input from a CAN controller.

2

GND Ground

3

VCC Supply Voltage. Bypass VCC to GND with a 0.1µF capacitor.

4

RXD 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

5

SHDN ground to utilize the AutoShutdown feature of MAX3050. See the Shutdown and AutoShutdown sections for a

full explanation of SHDN behavior.

6

CANL CAN Bus Line Low. CANL is fault protected to ±80V.

7

CANH CAN Bus Line High. CANH is fault protected to ±80V.

8

RS

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.
