All counter stages are master-slave flip- flops. The state of the stage advances one count on the negative clock transition of each input pulse; a high voltage level on the MR line resets all counters to their zero state. All inputs and outputs are buffered. Pinout CD54HC4020, CD54HCT4020 (CERDIP) CD74HC4020, CD74HCT4020 (PDIP, SOIC) TOP VIEW Ordering Information PART NUMBER TEMP.
