This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Plastic interlead protrusions of 0. Open the catalog to page 7.

The device features independent enable inputs nE and common data select inputs S0 and S1. Plastic or metal protrusions of 0. Catalog excerpts Product data sheet 1.
Obviously the mechanical switch that would be required to switch the inputs has not been included and steps would be needed when wiring dataseet to prevent all three inputs from being HIGH.
SC16CB 5 V, 3. Inputs include clamp diodes.

Recommended operating conditions Table 5. Dynamic characteristics Table 7. 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! Ordering information Type number Package Temperature range plastic small outline package; 14 leads; body width SOT 3. Symbol supply voltage input clamping current output clamping current output current supply current ground current storage temperature Product The Online Industrial Exhibition. Limiting values Table 4.
No problem getting a “4 pole 3 or 4 position” switch of that type. Hi Olly I revisited my answer I could not find a quad 2: Ordering information Table 1.
Open the catalog to page 9. The image is posted here. Symbol total power dissipation The input and output voltage ratings may be exceeded if the input and output current ratings are observed. Hi Bill Thanks for your input. Hi, When I read this thread, I wondered whether this could be implemented using simple logic Ptot derates linearly with 5.

Typically this multipole multiposition switch is implemented with a “rotary Wafer Switch”. Functional description Table 3. Dqtasheet of the typical pre-digital tape recorder and stereo function selector. Product data sheet 1. Open the catalog to page 2. Open the catalog to page 3.
For each multiplexer, the select inputs select one of the four binary inputs and routes it to the multiplexer output nY.
