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.
Features
■ Wide supply voltage range: 1.0V to 15V
