The CD4020BC, CD4060BC are 14-stage ripple carrybinary counters, and the CD4040BC is a 12-stage ripplecarry binary counter. The counters are advanced one counton the negaTIve transiTIon of each clock pulse. Thecounters are reset to the zero state by a logical “1” at thereset input independent of clock.Features Wide supply voltage range: 3.0V to 15V High noise immunity: 0.45 VDD (typ.) Low power TTL compaTIbility: Fan out of 2 driving 74Lor 1 driving 74LS Medium speed operaTIon: 8 MHz typ. at VDD = 10V Schmitt trigger clock input
