... RF bus noise. The incoming signal is output at the RX pin being connected to the J1850 link controller. If the TX input is idle for a certain time, then the AU5780A enters a low-power mode. This mode is dedicated to help meet ignition-off current draw requirements. The BUS_IN input comparator is kept alive in the low-power mode ...
