In the deutsch 9 pin obd interface for heavy trucks, some manufacturers use the pin F,G for J1939 protocol and some use it for J1708 protocol. I am trying to use a NLAS4684 analog switch with dual SPDT configuration to get the desired output based on the pins usage by manufacturers.
I am worried about connecting an Analog switch next to the vehicle BUS pin. Is it safe to connect this switch to the diagnostic port to route signals? The Rd_on for this switch is low and the current per channel is around 300mA.
