If not, could someone please explain in simple terms as to why not?

Dynamic characteristics Table 7. For each multiplexer, the select inputs select one of the four binary inputs and routes it to the multiplexer output nY. Ordering information Type number Package Temperature range plastic small outline package; 14 leads; body dattasheet SOT 3.
Hi Olly I revisited my answer I could not find a quad 2: Ptot derates datahseet with 5. 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!
Open the catalog to page 6. Hi Bill Thanks for your input. Limiting values Table 4. Open the catalog to page 5.
No problem getting a “4 pole 3 or 4 position” switch of that type. Typically this multipole multiposition switch is implemented with a “rotary Wafer Switch”.
Functional description Table 3. Product data sheet 1. Open the catalog to page 4.
SC16CB 5 V, 3. Catalog excerpts Product data sheet 1. Recommended operating conditions Table 5. Three Way by Harkumbar, on Flickr My question is this: Think of the typical pre-digital tape recorder and stereo function selector. The image is posted here.
Open the catalog to page 3. The multiplexor is a Dual 4: Inputs include clamp diodes.
Electrical engineering examples
The device features independent enable inputs nE and common data select inputs S0 and S1. 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 dafasheet inputs from being HIGH.
The same 4 address lines can be bussed to the othe multiplexor and decoder. Open the catalog to page 7. Symbol total power dissipation The input and output voltage ratings may be exceeded if the input and datasheeh current ratings are observed. Hi, When I read this thread, I wondered whether this could be implemented using simple logic Plastic interlead protrusions of 0.

Open the catalog to page 2. Gives you your 3 options. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
