Shift registers are binary registers with the capability to shift the data stored in them from one register to other. This system is used to transfer the data from one register to the other in order to be able to use the data for different purposes. The shift registers can be classified into two types, namely parallel and serial shift registers. The serial shift registers normally move data one bit at a time, while the parallel shift registers move the data multiple bits at once. The CD74HC195PWT is a type of serial, 4 bit to 24 bit, logic shift register.

The CD74HC195PWT, when used with suitable logic functions, can transfer the data from one register to another using shift/load operations. This logic is used as a means of multiplexing, parallel data access and various switching applications. The device can be used with different logic functions to achieve the desired results. The device comprises of an input register, a control register and an output register. The input register consists of the data inputs (D0-D3), the control register consists of the control pins (S, R,RC) and the output register consists of the output bits (QA-QD).

The CD74HC195PWT has a variety of application fields such as computer data transfer, digital display systems, automated testing, logic probe circuits, arithmetic and storage devices and binary counters. Computer data transfer applications include operating systems, firmware, graphics, multimedia and gaming. Digital display systems involve the use of LCDs, LEDs, VFDs and plasma displays in the control of data. Automated testing applications involve the use of analog and digital circuits to test the operation of a device. Logic probe circuits involve the use of logic gates to determine the status of the circuit. Arithmetic and storage devices use the shift register to hold data or to perform mathematical operations. Binary counters involve the use of shift registers to count events.

The working principle of the CD74HC195PWT is based on the shift and load operations. The shift operation occurs when the shift pin is in the logic level high. The data is shifted from the input register one bit at a time and is fed into the output register. The data is shifted out of the input register with the clock edge. The load operation occurs when the load pin is in the logic level high. The data is loaded into the output register from the input register depending upon the logic state of the clock level.

The CD74HC195PWT is a versatile shift register which is capable of a variety of applications. It is used in different fields such as computer data transferring, digital display systems and logic probe circuits. It operates on the basis of shift and load operations, where the data is shifted from the input register one bit at a time. It is a highly reliable and robust device with excellent thermal and electrical performance.
