Note 1: As defined by ISOSHDN, bus value is one of two complementary logical values: dominant or recessive. The dominant value
represents the logical 1 and the recessive represents the logical 0. During the simultaneous transmission of the dominant
and recessive bits, the resulting bus value is dominant. For MAX3053 values, see the truth table in the Transmitter and
Receiver sections.
Note 2: The ESD structures do not short out CANH and CANL under an ESD event while -7V < CANH, CANL < +12V.

Pin Description
PIN NAME FUNCTION
1 TXD Transmit Data Input. TXD is a CMOS/TTL-compatible input from a CAN controller.
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 from the physical bus lines CANH and CANL.
5 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.
6 CANL CAN Bus Line LOW. CANL is fault protected to ±80V.
7 CANH CAN Bus Line HIGH. CANH is fault protected to ±80V.
8RS
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.
