(VCC = +5V, RL = 60Ω, CL = 100pF, TA = +25°C, unless otherwise specified.)

NAME

FUNCTION

TXD

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

GND

Ground

VCC

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

RXD

Receive Data Output. RXD is a CMOS/TTL-compatible output from the physical bus lines CANH and CANL.

SHDN

Shutdown Input. Drive SHDN low to put the MAX3053 in shutdown mode. See the Detailed Description

section for a full explanation of SHDN behavior.

CANL

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

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

GND to control output slope. See the Mode Selection section.
