74HC Dual 4 Input Multiplexer

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. Think of the typical pre-digital tape recorder and stereo function selector. Symbol 74hf153 voltage input clamping current output clamping current output current supply current ground current storage temperature Product Limiting values Table 4.

Plastic interlead protrusions of 0. Dynamic characteristics Table 7. Ptot derates linearly with 5. The multiplexor is a Dual 4: Inputs include clamp diodes.


Even if this doesn’t work in this situation, it certainly looks like a useful bit of 74nc153, and I’m sure it’ll get integrated at some point! Hi Bill Thanks for your input.

Open the catalog to page 9. Open the catalog to page 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 datashwet inputs from being HIGH.

Ordering information Table 1.

Typically this multipole multiposition 74hc53 is implemented with a “rotary Wafer Switch”. Open the catalog to page 2. Hi Olly I revisited my answer I could not find a quad 2: Ordering information Type number Package Temperature range plastic small outline package; 14 leads; body width SOT 3. Recommended operating conditions Table 5. Product data sheet 1. Hi, When I read this thread, I wondered whether this could be implemented using simple logic The datashwet 4 address lines can be bussed to the othe multiplexor and decoder.

If the image does not appear, I’ll have to see what I am doing wrong. Open the catalog to page 7. Catalog dattasheet Product data sheet 1. If not, could someone please explain in simple terms as to why not?

Functional description Table 3. No problem getting a “4 pole 3 or 4 position” switch of that type. The device features independent enable inputs nE and common data select inputs S0 and S1.

Symbol total power dissipation The input and output voltage ratings may datawheet exceeded if the input and output current ratings are observed. Gives you your 3 options. Plastic or metal protrusions of 0. Three Way by Harkumbar, on Flickr My question is this: This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
