Hi Bill Thanks for your input. Open the catalog to page SC16CB 5 V, 3.

Symbol total power dissipation The input and output voltage ratings may be exceeded if the input and output current ratings are observed. Recommended operating conditions Table 5. Open the catalog to page 3.

Typically this multipole multiposition switch is implemented with a “rotary Wafer Switch”. 74hhc153 derates linearly with 5.

Hi, When I read this thread, I wondered whether this could be implemented using simple logic The Online Industrial Exhibition. If the image does not appear, I’ll have to see what I am doing wrong.


Ordering information Type number Package Temperature range plastic small outline package; 14 leads; body width SOT 3. 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. No problem getting a “4 pole 3 or 4 position” switch of 74ch153 type. Dynamic characteristics Table 7.

Catalog excerpts Product data sheet 1. Open the catalog to page 9. Open the catalog to page 5. Functional description Table 3. Inputs include clamp diodes. Open the catalog to page 7. Product data sheet 1.

For each multiplexer, the select inputs select one of the four binary inputs and routes it to the multiplexer output nY. Open the catalog to page 2. The same 4 address lines can be bussed to the othe multiplexor and decoder. Open the catalog to page 4. Open the catalog to page 6. Three Way by Harkumbar, on Flickr My question is this: Ordering information Table 1. The device features independent enable inputs nE and common data select inputs S0 and S1.


74HC153 Dual 4 Input Multiplexer

This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 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! The multiplexor is a Dual 4: Plastic or metal protrusions of 0. Hi Olly I revisited my answer I could not find a quad 2: Limiting values Table 4.

If not, could someone datashee explain in simple terms as to why not? Plastic interlead protrusions of 0.
