CD4021BCM belongs to the category of integrated circuits (ICs).
It is commonly used for parallel-to-serial data conversion.
The CD4021BCM is available in a standard 16-pin SOIC (Small Outline Integrated Circuit) package.
The essence of CD4021BCM lies in its ability to convert parallel data into serial data, making it suitable for various applications requiring data transmission and storage.
The CD4021BCM is typically sold in reels or tubes, with each reel or tube containing a specific quantity of ICs. The exact packaging and quantity may vary depending on the supplier.
CD4021BCM operates by shifting data from its parallel inputs to the serial output. The clock input (CP) controls the shifting process. On each clock pulse, the data is shifted one stage to the right. The parallel data inputs (D0-D7) are loaded into the register when the parallel load enable (PL) signal is active. The asynchronous reset (MR) input clears the register to its initial state when triggered.
CD4021BCM finds applications in various fields, including:
