I am exploring MUX509 in one of my application.
We are giving some 1 KHz signal (Some command ) to S3B input and getting the same waveform on DB. Also We are providing continuous 15V on S3A and same is received on DB.
Now whenever the 1KHz pulses received on the device (connected on DB) it sends back some signal (1KHz waveform) on same channel (DB).
I can see that I am not able to receive the back signal on S3B side. I have checked signal is present on DB, but not coming on S3B.
As per datasheet MUX509 is bidirectional can be have input /output.
What could be the reason behind it
