circuit that choose one input to output

[jadersc]

Hello everybody,

I would like to know which CI does receive 2 inputs and select one to output. For example, the input one is 4V DC and the input 2 is a pulse of 4V with 10kHz and I want to choose one of them to output.

Thanks.

Or perhaps a CD4053. Your question is very vague.
