Logic circuit components are intended to operate with digital signals, in which the physical quantity varies between two distinct values. Flip flops are one of the most basic, yet useful types of logic circuit elements. The MC74AC273NG is an 8-bit static shift register consisting of a master clock, 8 D-type flip flops and a buffered parallel load input. The device is capable of performing 8-bit parallel data transfer and serial data in and out.

When the Device is disabled, the Outputs are set to a High-Impedance state and the Outputs will not be AFFECTED.The MC74AC273NG can be arranged to produce many different logical operations such as shift register, counter and storage register. In this case, the device acts as a universal shift register, where it can be used to store and transfer 8 bits of data in parallel or serially.

Application of MC74AC273NG

The MC74AC273NG is used in applications requiring serial shifting or parallel storage of data such as microprocessors, microcontrollers, digital signal processing systems, display systems, programmable logic controllers and other applications using logic and microprocessors.

For example, in numerous smartphones, the MC74AC273NG can be used in programmable array logic controllers to store and transfer commanded data from the processor to the various drivers for the various components. It can also be used in life-monitoring systems to store and shift a large amount of data quickly, and to store/shift serial data from a remote controller as part of an advanced control systems.

Working Principle of MC74AC273NG

The MC74AC273NG has four main operating modes; normal, serial, parallel, and clock reset. In the normal mode, the master clock signal is applied to the clock input and the outputs are shifted serially with each positive clock edge. In the serial mode, the data is shifted out serially on each positive clock edge. In the parallel mode, the data is loaded into the device in parallel when the pin is low. In the Clock Reset mode, when the signal is low, the shift register is reset. The device can also be used in low-power applications, as it can be disabled when not in use by setting the Enable (EN) pin to high.

The MC74AC273NG is a very versatile and simple to use device, and is great for applications that require shifting and storage of data. It provides a cost effective way to transfer and store data and can be used in a wide variety of applications. Additionally, it can be used in low-power applications due to its ability to be disabled on the fly when not in use, conserving power and saving energy.
