MAX33054EASA+T

Overview

The MAX33054EASA+T is a +3.3V CAN transceiver designed for industrial applications, featuring extended ±65V fault protection on the CANH and CANL lines. It supports high-speed data rates up to 2Mbps and incorporates ±25kV ESD HBM protection alongside an input common mode range of ±25V. The device includes a standby (STBY) pin enabling low-current consumption modes and a slow slew rate option when a 26.1kΩ resistor connects STBY to ground. It operates with a logic supply voltage (VL) ranging from 1.62V to 3.6V and functions within a temperature range of -40°C to +125°C in an 8-pin SOIC package.

Feature Summary

• Extended ±65V fault tolerance protects against overvoltage conditions on bus lines.
• Integrated ±25kV ESD HBM protection ensures robustness during manufacturing and field maintenance.
• Standby mode reduces current consumption while maintaining receiver monitoring capabilities.
• Slow slew rate minimizes electromagnetic interference for use with unshielded cabling.

Applications

• Programmable Logic Controllers
• Industrial Automation Systems
• Building Automation Networks
• Smart Grid Equipment
• Motor Control Units

Procurement Notes

Verify the specific ordering suffix to confirm the package type and RoHS compliance status. Confirm that the required thermal management aligns with the specified junction-to-ambient resistance values for your board layout. Ensure the logic supply voltage matches the microcontroller interface requirements before finalizing procurement.

Selection Notes

Select this component when extended overvoltage protection and high common-mode rejection are critical. The MAX33054EASA+T is suitable for noisy environments where ground planes shift relative to each other. Consider the standby feature if power conservation is necessary during idle periods. Verify compatibility with the system's logic voltage levels using the VL pin.

Part Context

This part belongs to the MAX33053E/MAX33054E family of +3.3V CAN transceivers. The MAX33054E variant specifically provides a standby control pin, distinguishing it from the silent-mode MAX33053E. Both devices share identical electrical characteristics regarding fault protection and speed, targeting harsh industrial environments requiring reliable communication.

Replacement Considerations

The MAX33053EASA+ serves as a functional alternative if silent mode is preferred over standby mode. Verify pinout compatibility, as both utilize the same 8-pin SOIC configuration. Ensure that the application does not require the specific low-power standby functionality unique to the MAX33054E series.
