General Description
The CD4020BM CD4020BC CD4060BM CD4060BC are
14-stage ripple carry binary counters and the CD4040BM
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
