HCF4020B is an integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. HCF4020B is a series of 14-stage shift registers which can be used as programmable counters or dividers.
The HCF4020B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology, available in DIP and SOP packages. It functions as a ripple carry binary counter where all counter stages are master-slave flip-flops. The device features buffered inputs and outputs, a common reset line, and standardized symmetrical outputs. It supports medium-speed operation with a typical frequency of 16MHz at 10V supply voltage and offers fully static operation.
| Supply Voltage (Vop) | 3 to 20 V |

The typical maximum clock frequency is 16MHz at a supply voltage of 10V.
A high level on the RESET line resets the counter to its all zeros stage.
The quiescent current is 150 µA at 5V supply voltage.
