Hi there - I'd like to pass ISO 11898 (CAN) signals through an N-FET. I'm very comfortable using MOSFETs for power switching. This is the first time that I've wanted to pass a fairly quick signal through one though.
Can anybody tell me what I should be looking for here? What specs are important, and which aren't? I guess the main ones that I care about are the Rdson, and the various capacitances. I've yet to find a good diagram explaining what all the different capacitances are, unfortunately.
Thanks so much for your help!
