The HEF4021BT-Q100J is a logic-shift register with wide and versatile usage in digital circuits. The device has 8 data inputs, 8 outputs, and a Clock input (CP) for shifting data from input to output. Each circuit contains 8 D-type flip-flop elements, each of which is capable of storing a single bit information. By clocking the device, data can be conveniently shifted from data input to data output one bit at a time with each Clock phase.

The HEF4021BT-Q100J, being a low-power CMOS technology device, is especially suitable for use where low power operation is required and space is at a premium. It is specifically designed to operate at lower voltage levels than traditional logic-shift registers, providing superior performance in terms of power saving and reduced power dissipation. This makes the device an excellent choice for use in portable electronic devices.

The operating principle of the HEF4021BT-Q100J is based on the idea of an 8-bit shift register, which moves data from input to output one bit at a time on each Clock phase. The device has two Clock inputs, CP and CP\\, which must be connected to a Clock signal in order to allow the device to shift data. When the Clock signal (CP and CP\\) is Low, the device isolates both the data inputs and the data outputs from each other and the data is stored in the selected D-type flip-flops. When the Clock signal rises, data is shifted from the inputs to the outputs. Depending on the state of the Clock signal, the data can be shifted from either CP to CP\\ or from CP\\ to CP. This makes the device suitable for use in both synchronous and asynchronous operations.

The HEF4021BT-Q100J is also equipped with asynchronous active low Reset and Set inputs which can be used to initialise the device to either High or Low logic levels when needed. These inputs are active only while the Clock signal is Low, and they become inactive when the Clock signal rises. The Reset and Set inputs can be used to initialise the device when power is restored after a power interruption, or any other undesired reset condition.

The HEF4021BT-Q100J has wide application in digital signal processing systems and telecom equipment, as well as in digital applications in consumer electronic systems. The device is also particularly suitable for applications that require low power operation, such as notebook computers, mobile phones, and PDA\'s.In addition, the low-power platform of the device enables designers to incorporate other CMOS-compatible devices such as adders and multipliers, in order to make relatively complex digital circuits.

In summary, the HEF4021BT-Q100J is an excellent logic-shift register for use in various digital applications. The device is designed to operate at lower voltage levels than traditional logic-shift register, providing excellent power saving and reduced power dissipation, making it particularly well-suited for use in portable electronic devices. The device is capable of shifting data on a clock signal, and it has two input and two output terminals in order to enable both asynchronous and synchronous operation. The device also has active Low Set and Reset inputs which can be used to initialise the device when power is restored. As such, the HEF4021BT-Q100J is an optimal choice for use in digital signal processing systems and telecom equipment, as well as for consumer electronics applications.
