MAX3055ASD+T

Overview

The MAX3055ASD+T is a ±80V fault-protected and tolerant CAN transceiver designed for Controller Area Network (CAN) applications. It operates at a data rate of 125kbps with a built-in slope-control feature to support unshielded cables. The device features a supply voltage range of 4.75V to 5.25V and an operating temperature range from -40°C to +125°C. Packaged in a 14-pin SOIC, it includes three low-power modes accessible via STB and EN pins, along with thermal protection and current-limiting circuits.

Feature Summary

• Provides ±80V fault protection on CANH and CANL bus lines against electrical transients and overcurrent faults.
• Supports single-wire transmission mode with ground offset voltages up to 1.5V during specific failure conditions.
• Guarantees full wake-up capability during failure modes through the WAKE pin or bus line signals.
• Includes receiver input filters for high noise immunity and slope control to minimize RFI/EMC issues.

Applications

• Industrial HVAC systems
• Automotive networks requiring robust fault tolerance
• DeviceNet node implementations

Procurement Notes

Verify the component authenticity by checking the marking code and package integrity upon receipt. Confirm that the ordering suffix matches the lead-free/RoHS-compliant specification. Ensure the supplier provides traceability documentation consistent with Analog Devices manufacturing standards before integration into production.

Selection Notes

Select this model specifically for 125kbps CAN network designs requiring extended fault tolerance. The MAX3055 offers optimal performance for unshielded cable applications due to its integrated slope control. Compare against MAX3054 for higher speed requirements or MAX3056 for lower power 40kbps scenarios within the same family.

Part Context

This component belongs to the MAX3054/MAX3055/MAX3056 series of ±80V fault-protected CAN transceivers manufactured by Analog Devices. It shares pinout compatibility with industry-standard parts like the TJA1054 while offering enhanced fault management capabilities and dedicated low-power modes controlled by external logic signals.

Replacement Considerations

Public confirmed substitute part numbers include MAX3054ASD+T and MAX3056ASD+T from the same series. These alternatives share identical pin configurations and functional compatibility but differ in specified data rates and slope control characteristics.
