The CD4021BM is an IC that serves as a static shift register with 8 channels

CD4021BM Information

Description

The Texas Instruments CD4021BM is an 8-bit parallel-to-serial shifting register with a wide supply voltage range of 3V to 18V. It features eight parallel-in/serial-out stages, serial input pin for data input, clock input pin for shifting data, and buffered output. This device allows direct overriding of the set and reset functions via CLEAR and DATA pins. The CD4021BM is a versatile component that can be used in various applications such as shift registers, serial input/output expanders, keypads, microcontroller-based projects, industrial automation, and more.

Features

The CD4021BM features:

  • Eight parallel-in/serial-out stages
  • Serial input pin (DIP) for data input
  • Clock input pin (CP) for shifting data
  • Direct overriding of set and reset functions through CLEAR and DATA pins
  • Wide supply voltage range: 3V to 18V
  • Buffered output
  • Cascadable for multiple devices

Package

The package type of CD4021BM is SOP16 (Small Outline Package, 16 pins).

Pinout

The CD4021BM has a package type of SOP16, which means it has 16 pins.

Here's a concise summary of the pin functions:

  • Pins 1-8: Parallel input (data) pins
  • Pin 9: Serial input (DIP) pin for data input
  • Pin 10: Clock input (CP) pin for shifting data
  • Pin 11: Clear (CLR) pin to override set and reset functions
  • Pin 12: Data (DATA) pin to override set and reset functions
  • Pins 13-16: Output pins, buffered and cascadable

Note that the product description does not mention a specific pin count for the parallel input or output pins.

Manufacturer

The manufacturer of the CD4021BM is Texas Instruments (TI), a leading American technology company that designs, manufactures, and sells semiconductors and other electronic components. TI is a global leader in the development and manufacturing of analog and embedded processing technologies. The company was founded in 1930 and is headquartered in Dallas, Texas.

Applications

The CD4021BM is commonly used in applications requiring parallel-to-serial data conversion, such as shift registers and serial input/output expanders. It's also used in devices that need to read multiple digital inputs, like keypads or button arrays, and microcontroller-based projects for expanding the number of input pins available. Additionally, it can be used in industrial automation for monitoring and controlling various sensors and switches.
