The PI74LPT16374AV is a logic-shift register belonging to the family of CMOS shift registers which can be used in multiple applications ranging from memory through to data transmission.

This device is a low-power 16-bit shift register with an asynchronous serial input and synchronous serial output. It can be driven by either positive or negative clock edges, and it can be combined with other shift registers in order to expand the number of bits. It is suitable for use in data acquisition systems, field programmable gate arrays, memory expansion, data transmission and other digital systems.

This device has two functions: shift and hold. It has programmable shift direction capability which allows for either shifting in a left to right or right to left direction. The shift state of the device is maintained when put in the hold mode, which is useful for data transmission, synchronization and memory storage.

The working principle behind the PI74LPT16374AV is simply registration and release of a data bit by a clock pulse edge. It is composed of two dual 4-bit cascaded register-to-output flip-flops, forming an 8-bit shift register which is further cascaded to form a 16-bit shift register. It is the simplest type of type of shift register configuration. The device has an asynchronous serial data input and a synchronous serial output. The clock input is used to trigger the shift register to shift the data bit either left or right. The data bit is transferred to the output when the clock input is at low, or when the shifts left. When the shifts right, the data bit is transferred to the output when the clock input is at high.

In an application to data transmission such as FIFO buffer, the PI74LPT16374AV can be used to communicate data between two systems. The device is capable of latching data with a clock and shift the data so that the data can be transmitted in a full-duplex mode. It is also used in memory expansion applications where it serves as an address translator and can increase the internal address space by concatenating multiple 16-bit shift registers.

In the field of digital systems and data acquisition, it can be used to shift and store data bits which can then be used to generate signals or digitize analog data streams. It can also be used to scan keypads or to control displays. In addition, since the device consumes very low power, it can be used in a wide range of applications in which power efficiency is of great importance.

The PI74LPT16374AV is a versatile, low-power logic-shift register which is suitable for use in multiple applications ranging from data transmission, memory expansion and digital systems. It has a simple design and working principle and it is capable of shifting and latching data in a reliable and efficient manner.
