hi
pls anybody can help me in designing a 8 bit counter using 4 bit counter since i hav already designed a 4 bit counter. what is additional circuitry that is needed to cascade both counters and build a 8 bit counter.
connect the 'carry out' pin of the first to the 'clock' / 'count' pin of the next. When the first counter "overflows" ie is "1111", the carry bit will change to "1". If you don't have a carry bit use a 4 bit AND. Basic logic.
