I've got a projector that takes both component and VGA input on the same Dsub15 plug. I use a mechanical switch currently, which works, but it's a crappy solution, introduces a lot of noise, and sometimes has to be hit to work properly. Mechanical switches suck, and I wanted to go solid state with it.
I saw this:
**broken link removed**
and decided to build my own VGA switch.
As the MAX465 is not available anymore, I redid it using a MAX4026 (It's mislabeled as MA4026 in my schematic), adjusting the pinout from the project in the link, but when I power it up, nothing happens. I've only got an Component device hooked up to it right now, so the other two ICs are not currently being used.
The only things not shown on this schematic is that there are 0.1uF ceramic caps in various places, a capacitor on the negative output of the MAX660, and the MAX660's negative output is actually hooked up. For the bypass caps, there's one under the chip that only uses the 0/5 supply, and 2 under each that takes -5/+5.
