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.

5

SHDN

Shutdown Input. Drive SHDN low to put into shutdown mode. See the Detailed Description section 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.

Mode Select Pin. Drive RS low or connect to GND for high-speed operation. Connect a resistor from RS to

8

RS GND to control output slope. Drive RS high to put into standby mode. See the Mode Selection section under

Detailed Description.
