±80V Fault-Protected/Tolerant CAN Transceiver  
MAX3054/MAX3055/  
MAX3056  
General Description  
Features  
±80V Fault Protection  
The MAX3054/MAX3055/MAX3056 are interfaces  
between the protocol controller and the physical wires  
of the bus lines in a controller area network (CAN). The  
devices provide differential transmit capability and switch  
to single-mode if certain fault conditions occur. The  
MAX3054/MAX3055/MAX3056 guarantee full wakeup  
capability during failure modes.  
Low RFI/Excellent EMC Immunity  
Full Wake-Up Capability During Failure Modes  
Bus Failure Management  
Support Single-Wire Transmission Mode with  
Ground Offset Voltages Up to 1.5V  
The extended fault-protected voltage range of CANH and  
CANL bus lines of ±80V. Current-limiting and thermal-  
protection circuits protect the transmitter output stage  
against overcurrent faults to prevent destruction of the  
transmitter output stage. The CANH and CANL lines are  
also protected against electrical transients that may occur  
in rugged environments.  
Thermally Protected  
Do Not Disturb the Bus Line when Unpowered  
Low-Current Sleep and Standby Mode with Wake-Up  
Through Bus Lines  
Up to 250kbps Data Rate (MAX3054)  
Pin and Functionally Compatible with TJA1054  
The transceiver provides three low-power modes that  
can be entered and exited through pins STB and EN. An  
output INH pin can be used for deactivation of an external  
voltage regulator.  
Ordering Information  
The MAX3054/MAX3055/MAX3056 are designed to pro-  
vide optimal operation for a specified data rate. The  
MAX3054 is ideal for high data rates of 250kbps.  
The MAX3055 is used for data rates of 125kbps and  
the MAX3056 is designed for 40kbps applications. For  
40kbps and 125kbps versions, a built-in slope-control  
feature allows the use of unshielded cables, and receiver  
input filters guarantee high noise immunity.
