Working Principles

The HCF4021BM1 is a shift register IC that performs serial-to-parallel data conversion. It operates by shifting the input data bit-by-bit into its internal storage registers. The clock signal controls the shifting process, while the enable signal enables or disables the output stage. The parallel load input allows direct loading of data into the storage registers. The stored data can be accessed in parallel through the output pins.
