MCP2551-E/SN is a Microchip high-speed CAN physical-layer transceiver that connects a CAN protocol controller to a differential CANH/CANL bus. It supports data rates up to 1 Mb/s and operates from a recommended 4.5–5.5 V supply (5 V nominal).

The E/SN version provides an extended ambient temperature range of −40 to +125°C in an 8-lead SOIC package with a 150 mil body. The RS pin selects High-Speed, Slope-Control or Standby operation. Integrated protection includes thermal shutdown, bus short-circuit protection, power-on reset/brown-out protection and permanent-dominant TXD detection.

Use it for existing embedded and industrial CAN interface designs; a separate CAN controller is required. Microchip marks MCP2551 as not recommended for new designs and recommends reviewing MCP2561 for new projects.

Confirm package compatibility, actual lot markings, date code, packing and delivery terms with HONGTE before ordering. See the linked MCP2551 family datasheet for electrical limits and design guidance.
