MAX33042EASA+T

Overview

The MAX33042EASA+T is a +5V CAN transceiver in an 8-pin SOIC package. It supports data rates up to 4Mbps and operates within a supply voltage range of 4.5V to 5.5V. The device provides ±40V fault protection on CANH and CANL, ±40kV ESD Human Body Model protection, and an extended common-mode input range of ±25V. It features a dominant timeout mechanism, thermal shutdown, and low-current standby and shutdown modes. Operating temperatures range from -40°C to +125°C.

Feature Summary

• Integrated ±40V fault tolerance and ±40kV ESD HBM protection for robust industrial operation
• Transmitter-dominant timeout prevents bus lockup caused by controller errors or TXD faults
• Flexible power management with low-current standby mode and dedicated shutdown pin
• Slow slew rate capability via external resistor to minimize electromagnetic interference

Applications

• Industrial equipment communication networks
• Motor control systems
• Building automation controllers
• Instrumentation interfaces

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the component meets the required temperature range and electrical specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when high-speed CAN communication requires extended overvoltage protection and noise immunity. The ±25V common-mode range suits environments with significant ground potential differences. Consider the available packages based on PCB space constraints and thermal dissipation requirements for the specific design layout.

Part Context

This part belongs to the MAX33042 family of fault-protected CAN transceivers designed for harsh industrial environments. It complements other interface solutions by offering integrated protection features that reduce the need for external components. The device is manufactured by Analog Devices / Maxim Integrated.

Replacement Considerations

The MAX33042EAKA+T serves as a direct functional alternative utilizing an 8-pin SOT23 package instead of the SOIC format. Verify pinout compatibility and thermal characteristics when substituting between package types.
