The CD4517BEG4 integrated circuit (IC) is an example of a logic-shift register. It is a programmable shift register, allowing for 8-bits of data to be shifted with the longer 16-bit shift register. This IC can be utilized in a number of ways, from data access to serial communication. It is a versatile IC that can be used for a variety of applications.

Application Field

CD4517BEG4 is a powerful IC in many different types of applications. They are often used in data access devices, and can be found in many computers and other communication devices. It can also be used to store and move digital information through a logic circuit. This shift register is also used in serial digital communication as they facilitate the serialization and deserialization of data. Additionally, it is used in LED display systems, where a group of registers are used in combination to create a 4-digit BCD output.

Working Principle

The CD4517BEG4 shift register consists of three distinct sections. The first is a fully static section, or data register, which is used to store up to 8 bits of data. This register is loaded with data from an outside source. The second section is a static column-to-row select logic block, which selects a row that is to be shifted out of the shift register. The last section is the fully static master-slave register, which provides a shift pulse that moves the data down the shift register, from the data register to the master-slave register.

In order for data to move from the data register to the master-slave register, a shift clock is necessary. This shift clock is generated by an external pulse source and passes through the column-to-row select logic block before being applied to the shift register. The shift clock enables the data to move down the shift register one bit at a time, which is then loaded into the master-slave register.

The serial data stream can be taken from the master-slave register in two ways. The first is to take the serial output from the master-slave register directly. The second is to take the serial output from the master-slave register and add an additional delay of one shift pulse. This allows for a burst of 8-bit data to be taken from the shift register.

This shift register can be used for various applications. Its static column-to-row select logic block is particularly useful for selecting a specific row to output data, making it ideal for LED display systems. Additionally, its shift pulses can be used to move data through a serial communication line as well as a logic circuit. The CD4517BEG4 shift register is a powerful IC that can be utilized in many different types of applications.
