Logic - Flip Flops are fundamental components of digital systems. They are widely used in logical operations and memory elements due to their communication and memory feature. 74ABT377ADB,118 Logic - Flip Flop is a typical product of such kind of logic devices. This article will introduce its application field and working principle.

Essentially, 74ABT377ADB,118 Logic - Flip Flop consists of two half-adders and two latches connected in series. It is a typical abstraction of SR flip-flop, whose main features are set and reset operations. It requires two inputs in which one is called synchronous input and the other is asynchronous input. As long as the synchronous input is high, this flip-flop would keep in the same status without caring the asynchronous input. When the synchronous input is low, the flip-flop will operate according to the value of asynchronous input.

Generally, 74ABT377ADB,118 Logic - Flip Flop can be applied in several targets such as frequency division and conversion, clock pulse generation, shift registers and counters. Among these, frequency division and conversion is one of the most important applications. This flip-flop is able to produce high accurate output frequency by receiving the correct synchronous signal from the main clock. The relationship between the clock frequency and output frequency is determined by the number of the FlipFlops connected in series . In addition, flip - flop also plays an important role in designing several complicated control systems.

Another field of 74ABT377ADB,118 Logic - Flip Flop application is shift registers. It is a type of memory device composed of several flip-flops connected in series. This device is capable of taking several data as a parallel input in the beginning and outputting them one by one at different times. It is mainly used in timing measuring and signal accumulation.

Moreover, this flip-flop can also be used in designing several counters. Generally, there are two types of counters: Asynchronous Counter and Synchronous Counter. For asynchronous counter, the clock signal is only working on the first flip-flop while the rest of them will transfer data following the input from previous stage. However, the synchronous counter requires the whole FlipFlop under the same clock frequency. This type of counters are widely used in providing numerical information for data processing.

Next, the working principal of 74ABT377ADB,118 Logic - Flip Flop should be elaborated. When this flip- flop is connected to the power source, it will send out the inverting signal and non-inverting signal. The inverting signal is normally the output from the first latch and the non-inverting signal is from the other one. The two signals would interac together to produce the output signal. When the synchronous signal is high, no data would be transferred even the asynchronous signal changed creating stabilize output signal. When the synchronous signal is low, the values of synchronous and asynchronous signal would determine the output value.

In conclusion, 74ABT377ADB,118 Logic - Flip Flop is a widely used device in digital system. Its major applications include frequency division, shift registers and counters designing. It requires two inputs, which one is from the synchronous signal and the other one is from asynchronous signal. The output of flip-flop is determined by the combination of the two input values. These are the basics of its application field and working principle.
