Logic-shift registers are an essential part of modern digital communications and are used in a wide range of applications including data storage, digital video processing, and signal routing. The CD4021BMG4 is one such device and is a logic-shift 16-bit register designed for high-speed operation. This article will discuss the application field for the CD4021BMG4 and its working principle.

The CD4021BMG4 is suitable for applications such as digital data buses, multiplexers and signal routing. The device is well-suited for digital video processing which requires shift registers that can handle high data rates to support the processing of high-definition video. Additionally, the device can be used in data storage applications in which it serves to convert parallel data into serial signals. The CD4021BMG4 also offers low current consumption which makes it suitable for applications where implementation of long signal chains is necessary.

The CD4021BMG4 features four independent control inputs which can be used to configure the register. These inputs control the shifting of data and can be used to set the clock rate, the operating mode, or to reset the register. The device is capable of operation at clock rates up to 50 MHz and of transferring data at rates up to 100 Megabits per second. The device also contains a master reset input which is used to reset the output lines to their initial state.

At the heart of the CD4021BMG4 is a 16-bit shift register which is used to store and transfer digital data. The data is stored in the shift register in a modified serial format in which each bit can be shifted either in or out under control of the four independent control inputs. The shift register can be set up to operate in either a serial or a parallel mode and the direction of data flow can be controlled by the control inputs.

Once data has been written into the shift register, it can be read out of the device in either a serial or a parallel format. In a serial configuration, the data is shifted out bit-by-bit under control of the control inputs. The parallel output mode allows the full 16-bits to be read out simultaneously. The device is also capable of performing arithmetic operations, such as addition and subtraction, on the data stored in the shift register.

In addition to the above features, the CD4021BMG4 also contains an internal oscillator which can be used as a clock source for the device. The oscillator generates a stable clock signal and can be used in either a asynchronous or synchronous mode. The oscillator provides a clock frequency of up to 100 MHz and is capable of driving signals up to 25 MHz.

In summary, the CD4021BMG4 is a 16-bit logic-shift register designed for high-speed operations. It is suitable for applications such as data buses, multiplexers and digital video processing. The device offers four independent control inputs, an internal oscillator, and a master reset input which can be used to reset the output lines to their initial state. The device is also capable of performing arithmetic operations on the data stored in the shift register.
