Product Description: CD4021 SOP 8-Bit Static Shift Register with Asynchronous Parallel Load Input

The CD4021 SOP 8-Bit Static Shift Register is a CMOS-based integrated circuit designed to handle serial-to-parallel and parallel-to-serial data conversion. It features an 8-bit static shift register capable of serial input and parallel output, making it an essential component for applications requiring efficient data storage and transmission. The CD4021 is equipped with an asynchronous parallel load input, allowing the register to be loaded with data directly from the parallel inputs, making it versatile for various applications where data needs to be stored or shifted with precise timing.

This shift register operates in a serial mode, shifting data bit-by-bit with each clock pulse. When the parallel load input is activated, the 8-bit register can load data asynchronously, allowing rapid parallel data entry without waiting for the clock signal. This capability makes the CD4021 ideal for use in systems that need to interface with parallel data buses or work with both serial and parallel data formats.

The SOP-16 package ensures that the CD4021 is well-suited for surface-mount applications, offering compact dimensions and high reliability for integration into modern PCBs. The CMOS technology used in the IC ensures that it offers low power consumption, high noise immunity, and long-term stability.

Key Features:

  • 8-Bit Static Shift Register: The CD4021 features a static 8-bit shift register that enables serial-to-parallel and parallel-to-serial data conversion for digital applications.
  • Asynchronous Parallel Load Input: The parallel load input allows the 8-bit register to load data directly and asynchronously, enabling fast data entry without waiting for clock pulses.
  • Serial Data Input and Output: The serial input allows data to be shifted bit-by-bit into the register, while the parallel output provides a wide data path for efficient data retrieval.
  • Clocked Operation: The shift register shifts data on the rising edge of the clock signal, ensuring synchronized data processing for use in time-sensitive systems.
  • Low Power Consumption: Built using CMOS technology, the CD4021 is designed for low power consumption, making it ideal for battery-powered or energy-efficient systems.
  • Wide Voltage Range: The CD4021 operates over a voltage range of 3V to 18V, making it versatile for use in both low-voltage and standard logic applications.
  • Compact SOP-16 Package: The SOP-16 surface-mount package is compact, making it ideal for integration into space-constrained PCB designs and automated assembly lines.

Applications:

  • Data Storage and Transfer: The CD4021 is used in data storage and transfer applications, where data needs to be shifted between serial and parallel formats. It can store up to 8 bits of data, making it ideal for digital signal processing.
  • Digital Communication: The shift register is commonly used in digital communication systems to convert serial data to parallel data for processing or vice versa.
  • Microcontroller Interfacing: The CD4021 can interface with microcontrollers to provide parallel output from a serial input, useful in applications where microcontrollers need to process data sequentially.
  • Signal Processing: In signal processing applications, the CD4021 can be used for time delay circuits, signal filtering, or in systems where bitwise operations are performed on data.
  • Data Bus Expansion: The parallel load input allows the shift register to be used in data bus expansion systems, enabling efficient parallel-to-serial or serial-to-parallel data conversion.
  • Timing and Control Circuits: The CD4021 is used in timing or control circuits, where it can store data or act as part of a finite state machine for controlling complex systems.
  • Memory Systems: The shift register can also be used in memory systems for storing temporary data or as a component in shift-register-based memory systems.
  • Sequencers and Controllers: The CD4021 is used in sequencers or controllers that require data to be loaded and shifted for sequential operation in systems like counter circuits, stepper motor drivers, or event-driven systems.
  • Signal Demodulation: In digital communication systems, the shift register can be used in modulation and demodulation processes, where data is shifted in and out for encoding and decoding.
