• Industrial applications utilizing serial bus interfaces up to 20 kBaud
• Systems interfacing PIC microcontrollers via EUSART or standard USARTs

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SN' corresponds to the SOIC-8 package configuration required for your PCB layout. Confirm that the '330' designation matches the necessary 3.3V regulator output for your system design. Ensure the operating environment falls within the specified extended temperature range of -40°C to +125°C. Cross-reference the datasheet revision DS20002306B for the most current electrical characteristics and pin definitions before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a combined LIN transceiver and regulated power supply is needed to reduce external component count. The 3.3V regulator output is suitable for powering downstream microcontrollers directly. Consider the 8-pin SOIC package for ease of assembly if surface mount technology is preferred. Evaluate the 70 mA current limit against the peak consumption requirements of the connected MCU to ensure stable operation under all load conditions.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MCP2025 family of LIN transceivers designed for automotive environments. The '330' variant specifically provides a 3.3V regulated output, whereas other variants may offer 5.0V. The 'T' indicates tape and reel packaging, while 'SN' denotes the SOIC-8 package type. This family is engineered to meet stringent OEM hardware requirements for LIN, CAN, and FlexRay interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other MCP2025 variants such as MCP2025-500E/SN for a 5.0V regulator output. For different packages, check MCP2025-330E/ST for TSSOP options. Ensure any substitute maintains the same 20 kBaud speed, 43V protection rating, and AEC-Q100 qualification status.
