74HC4020-Q100; 74HCT4020-Q100 14-stage binary ripple counter Rev. 1 - 23 May 2013 Product data sheet 1. General description The 74HC4020-Q100; 74HCT4020-Q100 are 14-stage binary ripple counters with a clock input (CP), an overriding asynchronous master reset input (MR) and 12 buffered parallel outputs (Q0, and Q3 to Q13). The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. Each counter stage is a static toggle flip-flop.. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. This product has been qualified to...
