Abstract: An example common mode (CM) voltage clamp for a node of a multidrop network includes a first and second CM voltage dividers coupled to first and second lines of a differential link; a first N-type transistor coupled to the first line via a first diode, and further coupled to the first CM voltage divider; a second N-type transistor coupled to the second line via a second diode, and further coupled to the first CM voltage divider; a first P-type transistor coupled to a ground signal of the node via a third diode, and further coupled to the second CM voltage divider; and a second P-type transistor coupled to the ground signal of the node via a fourth diode and further coupled to the second CM voltage divider, where the second CM voltage divider is further be coupled to the ground signal via a fifth diode.
