Video switcher

[margaret mcghee]

I am trying to find a supplier in the uk for the maxim 454 video
multiplexer and amplifier ic to switch between 2 to 4 cctv cameras, i
came across an excellent cct for this purpose all the other parts are
readily available except the multiplexer ic, anyone know of a source.

Regards,
mat.

I have some video switch ICs that are controlled by the I squared C
bus. While it won't plug right in it for your circuit but these will
switch from any of 8 inputs to any of 6 outputs. The part number is TEA6417.
Thanks,
Phil Cline
