Details
The HCF4021B is an integrated circuit (IC) that serves as an 8-stage static shift register commonly used in digital applications. It is designed primarily for serial-to-parallel data conversion and can be found in various devices like counters, frequency dividers, and storage registers. The IC features a parallel-in, serial-out structure with a common clock input for shifting data from one stage to another.The HCF4021B operates on a supply voltage ranging from 3V to 18V and has a maximum clock frequency of 5 MHz. It can handle a maximum input voltage of 0 to VDD and provides Schmitt-trigger action on the clock input for improved noise immunity and performance. The IC also includes an asynchronous parallel load input for loading data directly into the register without requiring clock pulses.The HCF4021B comes in a 16-pin dual in-line package (DIP) and is widely available in the market for purchase. It is relatively easy to use and offers reliable operation in various digital circuit applications.
