Yes, I will be ensuring that only one scart bus is enabled at one time.
You are right, I am building a electrically controlled SCART switch of sorts. One output line, many inputs which will be controlled via an ESP32.
I am with my existing approach concerned about 'noise' from the other 3 connected buses even if they are not on, I feel it is possible some noise may be produced., not clear on the best way to separate these.
I don't believe the bus switch (FSTD16211MTDX) has an enable switch, unless you would call the OE1, and OE pins enable(which is what they appear to do) If 3 of the SCART buses are sending OE1, OE2 low, to turn of the bus, only one SCART will be connected to the output. Will I get noise? If so, how can I remove that?
