CD4066 for av switching

[Trevors]

Hi everybody,
I would like to use the 4066 to switch av inputs as I have more than one device to connect to my television but the television has only one set of av inputs. Will this chip be suitable for this?

hi,
The basic 4066 is ok for A/V, you may see some reduction in picture quality however.

You can purchase low cost auto switch over boxes, about £8GBP.
These usually have 4 A/V inputs with a common output to the TV.etc.

Hi Eric,
Thanks for the reply. I searched on the net and found a simple circuit using relays to do the switching.
