MCP25055-I/SL

2.7V~5.5V,1Mbps,CAN I/O扩展器,3Tx/2Rx

Description

The MCP2502X/5X devices operate as I/O expanders for a Controller Area Network CAN system, supporting CAN V2.0B active, with bus rates up to 1 Mb/s. The MCP2502X/5X allows a simple CAN node to be implemented without the need for a microcontroller.
