SN74LVCC4245ANSR
This Texas Instruments device is designed for high-speed voltage translation between 3.3V and 5V domains. Its SOP‑24 package is well suited for supporting multiple SPI signals (SCK, MOSI, CS, and possibly MISO) while maintaining bidirectional communication. -
74LVCH2T45GN,115
The Nexperia part supports low-voltage operation on one side (3.3V) and handles 5V on the other. Its bidirectional function and XSON‑8 footprint make it a good alternative for your SPI level shifting needs.
Both parts are highly capable of managing the speed and voltage levels required for SPI interfacing between an ESP32-S3 and an MCP2515. Feel free to review each part and select the one that best fits the layout and availability in your project.
