Frequently Asked Questions
Is this a CAN controller?
No. It has no protocol engine. It sits between a CAN controller and the bus wires and handles the electrical side, which is why Philips called it a CAN controller interface and distributors list it as a CAN transceiver.
What does pin 8 do?
Rs is the mode-select and slope-control pin.
Is this the through-hole DIP version?
No. The T in PCA82C250T marks the SO8 surface-mount version; the DIP8 is the PCA82C250 without the T.
A CAN controller knows the protocol but cannot drive a wire; the 82C250 is the part that puts its messages onto the two bus lines and hears the replies. Give each node one and let them talk.
