• Features ±60V overvoltage fault protection on data transmission lines across all operational modes.
• Supports high-speed CAN FD operation with data rates up to 4Mbps.
• Includes variable slew rate driver with active symmetry control and SPLIT pin for low electromagnetic emission.
• Offers extended common mode range of ±36V at 5V supply and ±25V at 3.3V supply.

Drivers, Receivers, Transceivers Applications

• Automotive and transportation electronics
• Industrial control and instrumentation networks
• Building automation, security systems, and HVAC

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the MP grade designation ensures the extended temperature range of –55°C to 125°C. Cross-reference the DD package code with the manufacturer's official documentation to ensure correct physical dimensions and thermal characteristics for the design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when ±60V fault tolerance and high ESD immunity are required in harsh environments. The MP grade is necessary for applications exceeding standard industrial temperature limits. Ensure the system voltage aligns with the 3.3V or 5V operating ranges, avoiding the discontinuity region between 3.6V and 4.5V.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2875 series of robust CAN transceivers. The MPDD variant specifically denotes the military/extended performance grade housed in an 8-lead DFN package. It shares functional compatibility with other LTC2875 variants but offers a wider operating temperature range suitable for demanding conditions.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include LTC2875IDD#PBF for industrial temperature ranges and LTC2875HDD#PBF for high-temperature industrial use. For SO-8 packages, consider LTC2875MPS8#PBF. Verify pinout and electrical specifications match before substitution.

Drivers, Receivers, Transceivers FAQ

What is the maximum data rate supported by the LTC2875?

The LTC2875 supports a maximum data rate of 4Mbps, enabling high-speed protocols based on the CAN physical layer and Flexible Data Rate (CAN FD).

How does the RS pin function regarding shutdown and slew rate?

A voltage on RS higher than VIH_RS places the chip in shutdown. A voltage below VIL_RS enables the chip. Pulling RS low through a resistor controls the slew rate, with RSL ≤ 4kΩ recommended for high-speed communication.

What is the purpose of the TXD dominant timeout function?

The TXD dominant timeout function limits the time the transmitter holds the bus in the dominant state to approximately 2ms (typical), preventing bus lockup if TXD remains low continuously.
