7490 is a Binary coded decimal counter and counts up to ten digits. Being binary counter it counts in binary digit like 0000, 0001, etc. The IC contains 4 master-slave flip-flops and some gating circuits to provide a divide-by-two counter and three-stage binary counter for which counter is divided by 5. The counter circuit gets reset for every new clock
