can anyone give me a hand on building an Auto AV Selector 4 input
like the one featured on www.lik-sang.com?....Oh it doesnt have to be 4 input just 2 at minimum
OK, so just connect one more 4066 IC for the video signal.
Then you will have an Auto AV selector for 4 sources. If you really must have 2 sources, then connect C and D inputs to ground and they will be skipped.
