The device features independent enable inputs nE and common data select inputs S0 and S1. No problem getting a “4 pole 3 or 4 position” switch of that type. Open the catalog to page 7. Ordering information Table 1.

Limiting values Table 4. For each multiplexer, the select inputs select one of the four binary inputs and routes it to the multiplexer output nY.

Typically this multipole multiposition switch is implemented with a “rotary Wafer Switch”. Ordering information Type number Package Temperature range plastic small outline package; 14 leads; body width SOT 3. Hi, When I read this thread, I wondered whether this could be implemented using simple logic Symbol total power dissipation The input and output voltage ratings may be exceeded if the input and output current ratings are observed.


Plastic or metal protrusions of 0. Dynamic characteristics Table 7. Hi Bill Thanks for your input.

This enables the use of current limiting resistors to interface inputs to voltages in excess of Datashet. Catalog excerpts Product data sheet 1. Open the catalog to page 3. Open the catalog to page 2. Think of the typical pre-digital tape recorder and stereo function selector.

Ptot derates linearly with 5. Even if this doesn’t work in this situation, it certainly looks like a 74hx153 bit of kit, and I’m sure it’ll get integrated at some point! Gives you your 3 options.

The multiplexor is a Dual 4: Plastic interlead protrusions of 0. SC16CB 5 V, 3. Open the catalog to page 5. Open the catalog to page 9. Open the catalog to page 4. The Online Industrial Exhibition.

Product data sheet datasheet. Inputs include clamp diodes. Three Way by Harkumbar, on Flickr My question is this: The same 4 address lines can be bussed to the othe multiplexor and decoder. Open the catalog to page Open the catalog to page 6. Functional description Table 3.

Open the catalog to page 8. If the image does not appear, I’ll have to see what I am doing wrong. Hi Olly I revisited my answer I could not find a quad 2: Symbol supply voltage input clamping current output clamping current output current supply current ground current storage temperature Product If not, could someone please explain in simple terms as to why not?

The image is posted here. Recommended operating conditions Table 5. 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.
