Frequency divisions up to 18,384 can be performed with the basic configuration of a 4020 as shown in Figure bellow. The outputs can be combined with logic gates to give intermediate values and/or high values. For instance, an AND gate connected to the 213 and the 214 does division by 24,578. The count advances one count with the positive transition of the clock. Notice that there are no outputs for the second and third stages. The counters are reset to zero by a “’1 " applied to the RST input. The maximum input frequency is 10 MHz when the circuit has a power supply of 10 V.
