Is there a way to test if an IC is "dead", or if its me going wrong with the pin connections?
Please post the part number.
common way to test ICs is to plug them into working circuit.
this is obviously dependent on used IC.
Power it as spec'd in the spec sheet. Note if supply current is within spec as spec'd in the spec sheet.
Apply appropriate inputs as spec'd in the spec sheet.
Observe outputs for appropriate values as spec'd in the spec sheet.
If Icc or some output is not within spec sheet range the IC may be bad or your setup/measurement technique should be reviewed.
Notice my emphasis! The spec sheet is your friend!
Also more often called datasheet.
Many thanks to each and all. I fully appreciate the"spec" and "data" sheets in fact that is where most of my limited knowledge comes from. I have returned to this one time hobby for the sake of my grandchildren. Having got this 4029 sort of working, I realise my limitations to be eyesight (wires in the wrong holes on the breadboard), and greymatter (Takes more time to remember how easy it once was). Thanks again.
