The Microchip MCP2551T-I/SN is a half-duplex CAN transceiver serving as the physical-layer interface between a CAN protocol controller and the differential bus.
The half-duplex architecture means the same pair of bus pins handles both transmit and receive, so the protocol controller must manage bus arbitration — standard for CAN 2.0B networks.
The silicon and electrical ratings are identical. The T suffix specifies tape-and-reel packaging (MCP2551T-I/SN) versus tube or bulk (MCP2551-I/SN). Both are the same 8-SOIC footprint and share the same datasheet.
Yes. The transceiver is designed for CAN 2.0B networks operating at that nominal voltage.
