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
s Wide supply voltage range: 3.0V to 15V s High noise immunity: 0.45 VDD (typ.) s Low power TTL compatibility: or 1 driving 74LS s Schmitt trigger clock input Fan out of 2 driving 74L
s Medium speed operation: 8 MHz typ. at VDD = 10V

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices should be operated at these limits. The tables of "Recommended Operating Conditions" and "Electrical Characteristics" provide conditions for actual device operation. Note 2: VSS = 0V unless otherwise specified.
