HCF4020B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. 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.
The HCF4020B is a monolithic integrated circuit fabricated in MOS technology, offered in DIP‑16 and SOP‑16 packages. It functions as a 14‑stage ripple‑carry binary counter with fully static operation, common reset, buffered inputs and outputs, and standardized symmetrical output.
The document lists absolute maximum ratings, recommended operating conditions, DC specifications, dynamic electrical characteristics, test circuit diagrams, and mechanical data for both plastic DIP and tape‑and‑reel SOP packages, enabling designers to integrate the device into a wide range of timing and counting applications.
