I have been trying to get my head round this for a while now but I can't seem to get it to work.
My specifications:
4 Inputs
1 reset
1 output
^^^^^^ times 4
inputs are active low
reset is active high
I want my system to default to output HIGH when all the inputs are HIGH and if any inputs are LOW then I want my system to output LOW and hold that value forever, until the reset is pressed where it will again output HIGH if all the inputs are HIGH. also, if the reset is held HIGH it would be nice for the output to be held HIGH also although this feature is not necassery.
I was using some dual 4 input NAND gates and some D type flip-flops but I would really like to know how you guys would go bout this problem avoiding a micro controller and preferably using 4000 series logic?
Thank you in advance for your help,
Billy
