MAX14883EASA+

Drivers, Receivers, Transceivers Overview

The MAX14883EASA+ is a high-speed CAN transceiver designed for industrial networks. It operates from a single 5V supply (VDD: 4.5V to 5.5V) with a logic-level supply input (VL: 1.71V to VDD). The device supports data rates up to 1Mbps and features ±60V fault protection on the CANH and CANL bus lines, along with a ±25V functional common mode input range. It includes selectable polarity control via the POL pin to correct cross-wired cables and a transmitter dominant timeout (tDOM) to prevent bus lockup. ESD protection ratings are ±22kV HBM, ±15kV IEC Air Gap, and ±10kV IEC Contact Discharge on the bus pins. It is housed in an 8-pin SOIC package and operates over a temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±60V fault tolerance on CANH and CANL bus lines for robust communication in harsh environments.
• Selectable polarity control input allows software correction of cross-wired field cables by swapping CANH and CANL I/Os.
• Transmitter dominant timeout mechanism prevents bus lockup caused by controller errors or TXD input faults.
• High electrostatic discharge protection on bus pins ensures reliability against human body model and IEC contact/air gap discharges.

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type matches the required 8-pin SOIC footprint. Ensure the operating voltage requirements align with your system's 5V power rail and logic level needs. Cross-reference the specific suffix to confirm the tape and reel packaging if applicable.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing CAN networks requiring high fault tolerance against short circuits and extreme common mode voltages. It is suitable for applications needing flexible logic interfacing with voltages as low as 1.71V. Consider the thermal shutdown feature for environments prone to sustained bus faults. Verify that the network topology and capacitive loading support the desired data rate performance.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14883 family of CAN transceivers from Analog Devices / Maxim Integrated. It is specifically engineered for industrial applications where standard transceivers may fail due to electrical noise or wiring errors. The inclusion of polarity selection distinguishes it from basic models, offering easier installation and maintenance in complex field deployments.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements must match the 8-pin SOIC package and provide similar ±60V fault protection. Check for compatible logic supply ranges and data rate capabilities. Ensure any substitute also offers polarity selection if cable reversal correction is required in the design.

Drivers, Receivers, Transceivers FAQ

How does the polarity selection input function?

Driving the POL pin high swaps the CANH and CANL I/O functions, allowing the device to operate correctly even if the field cables are cross-wired. Driving it low maintains normal operation.

What is the purpose of the transmitter dominant timeout?

The tDOM feature prevents the bus from being locked in a dominant state if the TXD input remains low for too long. It automatically switches the driver to the recessive state to release the bus.

What are the ESD protection levels for the bus pins?

The CANH and CANL pins offer ±22kV Human Body Model, ±15kV IEC 61000-4-2 Air Gap, and ±10kV IEC 61000-4-2 Contact Discharge protection.
