The 74HC/HCT4020 are 14-stage binary ripple counters
with a clock input (CP), an overriding asynchronous
master reset input (MR) and twelve fully buffered parallel
outputs (Q
The counter is advanced 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.
