General Description
The CD4020BC, CD4060BC are 14-stage ripple carry
binary counters, and the CD4040BC is a 12-stage ripple
carry binary counter. The counters are advanced one count
on the negative transition of each clock pulse. The
counters are reset to the zero state by a logical “1” at the
reset input independent of clock.
