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. Recommended operating conditions Table 5. Limiting values Table 4.
Ordering information Type number Package Temperature range plastic small outline package; 14 leads; body width SOT 3. Inputs include clamp diodes. Plastic interlead protrusions of 0.
The same 4 address lines can be bussed to the othe multiplexor and decoder. Catalog excerpts Product data sheet 1.
This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Open the catalog to page 9. 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. Functional description Table 3. Hi Bill Thanks for datashfet input.

Open the catalog to page 3. Typically this multipole multiposition switch is implemented with a “rotary Wafer Switch”. Hi Olly I revisited my answer I could not find a quad 2: Open the catalog to page Hi, When I read this thread, I wondered whether this could be implemented using simple logic Plastic or metal protrusions of 0. Open the catalog to page 6.
The image is posted here. The Online Industrial Exhibition. 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 7. For each multiplexer, the select inputs select one of the four binary inputs and routes it to the multiplexer output nY.
The multiplexor is a Dual 4:
