The chip represent a BCD number in relation to what the inputs are, in order of their priority A8 has the highest prority. That pretty much does it all for you. I think what he was meaning was even if you can’t design the full circit, see 74hf147 you can do your self. Test your settings by visiting www.

In the olde days this would have been done using diodes.

Mouser Electronics ha deshabilitado 74hc datasheet 1. My specific problem is how a 10 position switch needs to be wired to the encoder to obtain the required input to obtain the desired output at the display. OR Google it if you don’t Every system has an input, process and an output.

Then we can help you tie up the loose ends. To participate you need to register.

I’m fairly certain I understand the circuit for putting the encoder and the BCD decoder together. Can get expensive though: Welcome to our site! Get the data sheet for these parts.

You connect a diode from each contact on your rotary switch to the required segments on the display. Pruebe sus configuraciones visitando: Features, Applications For a complete data sheet, please also download: Essentially, converting the truth table into a circuit for a 10 position switch.

After you have the block diagram, start converting it into a circuit by using the datasheets. However, there are a few with shafts.
