I have a 3rd party board with a AM26LV31EIDR transmitter. It sends a signal to my board on which I have a AM26LV32EIDR receiver. If the 3rd party board loses power will the output of the AM26LV32EIDR receiver on my board go to a fail-safe condition (high or low)? Or do I need to add an external fail-safe bias network to ensure this?
