It integrates one driver and one receiver, uses a 4.5V to 5.5V supply rail, and provides 200 mV of receiver hysteresis for noise rejection on the bus. ## Package and footprint for tight layouts Housed in an 8-TDFN (2x3 mm) package with an exposed pad, the part requires a thermal land on the PCB — the datasheet recommends a 1.6 x 1.6 mm pad with four vias to the ground plane for heat sinking. The supply voltage tolerance (4.5V–5.5V) means a 5V nominal rail with ±10% margin stays inside the operating window; no external regulator is needed if the bus-side supply is clean. ## Active lifecycle and sourcing posture Available in Tape & Reel (TR) or Cut Tape (CT) for prototyping; the 8-TDFN package is compatible with standard reflow profiles used for lead-free assemblies.","metaTitle":"MCP2557FDT-H/MNY CAN Transceiver – Active, 150°C, 8-TDFN","metaDescription":"Microchip MCP2557FDT-H/MNY CANbus transceiver, 1/1 driver/receiver, 4.5V–5.5V supply, 200 mV hysteresis, -40°C to 150°C, 8-TDFN (2x3).
