MAX13054ASA+

Drivers, Receivers, Transceivers Overview

The MAX13054ASA+ is a high-speed CAN transceiver in an 8-pin SO package, operating from -40°C to +125°C. It features ±80V fault protection on CANH/CANL and ±8kV ESD protection. The device supports data rates up to 1Mbps with a dominant timeout function. A dedicated VCC2 logic supply enables full compatibility with +3.3V microcontrollers while the main supply operates at +5V. Standby mode reduces current consumption, and thermal shutdown protects against overheating.

Drivers, Receivers, Transceivers Feature Summary

• Dedicated VCC2 pin for direct +3.3V logic interfacing
• Extended ±80V fault protection on bus lines
• Dominant timeout prevents bus clamping errors
• Thermal shutdown and short-circuit protection

Drivers, Receivers, Transceivers Applications

• DeviceNet nodes
• Medium- and heavy-duty truck systems
• Industrial networks requiring overvoltage protection

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' indicates the extended temperature range of -40°C to +125°C compared to the 'E' variant. Confirm the '+T' or standard packaging requirements if ordering in reels versus tubes. Ensure the VCC2 pin is properly decoupled to GND with a 0.1µF capacitor close to the IC for stable +3.3V logic operation.

Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing a +5V CAN transceiver with a +3.3V microcontroller without level shifting. The separate VCC2 supply eliminates propagation delay associated with voltage translation. Verify that the application requires the specific +125°C automotive/industrial rating rather than the commercial grade.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13050/MAX13052/MAX13053/MAX13054 family of industry-standard high-speed CAN transceivers. All members share pin-for-pin compatibility and core features like ±80V fault protection. The MAX13054 is distinguished by its dual-supply architecture designed specifically for mixed-voltage logic environments.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include TLE6250v33 and CF163. These alternatives provide similar +3.3V logic compatibility and CAN functionality but may differ in specific electrical characteristics or package availability.

Drivers, Receivers, Transceivers FAQ

How does the MAX13054 handle +3.3V logic?

It uses a separate VCC2 input pin to power the digital I/O interface, allowing direct connection to +3.3V microcontrollers while the main VCC remains at +5V.

What is the purpose of the dominant timeout?

If the TXD input stays low for more than 1ms, the transmitter disables and drives the bus recessive, preventing a hung controller from blocking the network.

Does the MAX13054 support standby mode?

Yes, driving the STBY pin high places the device in standby mode, shutting off the transmitter and reducing supply current significantly.
