The CD4021BM is a shift register device from Texas Instruments that works with the logic gates of the CMOS family. It is part of the logic family of shift registers, so it\'s capable of shifting data or serial inputings through its internal registers or output pins. This allows the user to move data stored in the register and to communicate with multiple devices that are connected to it. The shift register also provides an asynchronous reset option, making it easier to reset the device when required.

The CD4021BM contains 8 flip-flop registers and 1 output latch, allowing the user to move data 8 bits(registers) or one bit(latch) at a time. It features two serial data inputs, standard (DS) and composite (Dc), which can be used to pass serial data from one register to the next. The device additionally has asynchronous clear and reset inputs, active low, which clear all registers to zero and reset them to their initial state. These reset and clear pins can also be used to switch between multiple patterns.

The output of the CD4021BM can be divided into three sections: parallel outputs, serial output, and tri-state output. The device parallel outputs are each individually 3-state active low and can be used to store data or input information to external circuits. The serial output is an active low output which is used to serially interconnect data to another register stage. Lastly, the tri-state output enables the user to switch between output modes, either active high/low or high impedance.

The CD4021BM is capable of working in both cold active (static) and hot active (power) modes. In static mode, the device powers up with the output pins in the active high or low state depending on the initial conditions. In power mode, the device allows the user to change the internal output states and corresponding output pins. Additionally, the static power consumption is low, making it suitable for low-power applications.

The CD4021BM can be used in a variety of different applications, including clock synchronization, data transmission, samplers, memory storage, Multiplexers, and LED displays. It can also be used in combinational logic, to move data from one device to another device over a data bus. In addition, the device could be used in arithmetic logic units, to shift the data from one register to another, making it easier to process information. Furthermore, the device has been used in industrial applications, like robotic controllers and automated systems.

In conclusion, the CD4021BM is a versatile shift register device that provides an asynchronous reset and clear option, allowing the user to quickly reset or clear all registers. It has two serial inputs, a parallel output, serial output, and tri-state output which can be used to transfer data. Lastly, the device can be used in a wide range of applications, from serial communication to industrial automated systems.
