The HEF4021BT,652 is a Logic - Shift Register. It provides a high degree of integration at basic levels, making it suitable for a wide range of applications. Specifically, the device has been designed to be used in applications that require low power consumption and minimized start-up time.

The HEF4021BT,652 is a 16-bit shift register with an internal bidirectional interface that can be used to interface with a number of simple logic devices. The device consists of two 8-bit registers and a counter/ offset logic to enable data to be shifted from one side of a device to another. The device also includes an enable/disable input and an overflow reset output for additional control.

The HEF4021BT,652 is powered by a 5V supply and requires a minimum of 2.5V for operation. It is rated for a maximum 25 mA current, with a typical capacitance of 1.5μF. It has a maximum data rate of 3Mbps and can operate at temperatures from -40°C to +85°C.

In terms of its application field, the HEF4021BT,652 can be used in a variety of applications. These include LED matrix displays, data keypads, temperature sensing, and other simple logic functions. The device is also well-suited to time-division multiplexing in telecommunication and automotive applications.

The working principle of the HEF4021BT,652 is based on the principle of shift registers. A shift register is a type of digital logic device that is used to store, transmit, and process information. At the center of the shift register is a series of 8-bit registers, which are interconnected and are used to store data. This data is moved through the device using two different mechanisms. The first is by serial shifting, through which data is moved one bit at a time from one register to the next. The second is by parallel shifting, where the data is shifted in a single step from one register to the next.

The HEF4021BT,652 has two different modes of operation: serial and parallel shifting. In serial mode, the register can be configured for either input or output of data. Data is shifted out of the register on a rising edge of the Clock signal, while data is shifted into the register on the falling edge of the Clock signal. In parallel mode, the entire data word is moved at once, while the Clock signal only shifts individual bits within the register.

The HEF4021BT,652 is a versatile logic device with a wide range of applications. Its low power consumption, small size, and high degree of integration make it an ideal choice for a variety of tasks. Its serial and parallel mode options allow for flexible data transmission and easy implementation into existing systems. With its advanced features, the HEF4021BT,652 is an ideal choice for those looking to create reliable, efficient, and cost-effective systems.
