... Recessive states correspond to the Low and High state of the TXD input pin, respectively. However, a Dominant state initiated by another CAN node will override a Recessive state on the CAN bus. 1.1.1 MAXIMUM NUMBER OF NODES The MCP2551 CAN outputs will drive a minimum load , of 45Ω allowing a maximum of 112 nodes to be connected (given ...

... TXD Permanent Dominant Detection If the MCP2551 detects an extended Low state on the TXD input, it will disable the CANH and CANL output drivers in order to prevent the corruption of data on the CAN bus. The drivers are disabled if TXD is Low for more than 1.25 ms (minimum). This implies a maximum bit time of 62.5 µ ...
