No problem getting a “4 pole 3 or 4 position” switch of that type. If not, could someone please explain in simple terms as to why not?

Open the catalog to page Open the catalog to page 2. Three Way by Harkumbar, on Flickr My question is this: Symbol total power dissipation The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

Gives you your 3 options. Obviously the mechanical switch that would be required to switch the inputs has not been included and steps would be needed when wiring it to prevent all three inputs from being HIGH.


Functional description Table 3.

For each multiplexer, dataheet select inputs select one of the four binary inputs and routes it to the multiplexer output nY. Catalog excerpts Product data sheet 1.

If the image does not appear, I’ll have to see what I am doing wrong. The multiplexor is a Dual 4: Open the catalog to page 7. Product data sheet 1. Think of the typical pre-digital tape recorder and stereo function selector.

This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Recommended operating conditions Table 5.

Plastic interlead protrusions of 0. The same 4 address lines can be bussed to the othe multiplexor and decoder. Even if this doesn’t work in this situation, it certainly looks like a useful bit of kit, and I’m sure it’ll get integrated at some point!
