Abstract
A communication node including drivers for applying a switched signal to a communication line such as a CAN bus or a LIN bus, with a controlled slew rate. The driver comprises a series of transfer elements and a series of delay elements for cumulatively establishing operational connections of the transfer elements with the communication line, whereby to apply the switched signal progressively to the communication line. A feedback loop is responsive to the signal that the driver applies to the communication line for controlling the delays of the delay elements so as to control the delays with which the operational connections of the transfer elements with the communication line are established.
