DESCRIPTION
The HCF4020B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. The HCF4020B is a ripple carry binary counter.All counter stages are master-slave flip-flops.The state of a counter advances one count on the negative transition of each input pulse;a high level on the RESET line resets the counter to its all zeros stage.Schmitt trigger action on the input pulse line permits unlimited clock rise and fall times.
All inputs and outputs are buffered
