WebThe circuit shows a simple 00 to 99 digital counter using a 74LS390 BCD Counter and two 74LS47 7-segment display drivers. To count above 99, we would need to cascade more counter circuits together. A 4-digit BCD counter would count in decimal from 0000 to 9999 and then reset back to 0000. lynne schaber seaworld
