CD4020 14-Stage Binary/Ripple Counter - Datasheet

The CD4020 is a 14-stage ripple carry binary counter. The IC is a part of the CD4XXX IC series. CD4020 counters advance one count on the negative transition of each clock pulse. The counters are reset to the zero states by a logical “1” at the reset input independent of the clock. The IC offers a wide variety of features such as high noise immunity, low thermal dissipation, and ESD barring. Each I/O pin of the IC is protected from static damage by the use of I/O clamping diodes. The output of the IC always comes in TTL, which makes it easy to interface with other CMOS and TTL devices such as MCUs and MPUs

What is a Binary Ripple Counter?

A binary ripple counter generally uses a bistable multivibrator circuit so that cache input applied to the counter causes the count to advance or decrease. The Q and Q output terminals are always logically opposite. If the Q output is logical 1 (SET), the Q output then logical 0, If the Q output is logical 0 (REST), then the output is logical 1.A simple Binary ripple counter can easily be made by rigging at least two D - type flip flops.
