Flip-flop is an important logical element of modern digital circuit. It is widely used in digital system and digital circuit, such as counter, data storage and so on. With the rapid development of digital technology, the application of flip-flop is becoming more and more extensive. The 74ALVCH162721DLG4 is a kind of flip-flop.

Application Field of 74ALVCH162721DLG4

The 74ALVCH162721DLG4 is a kind of dual edge-triggered flip-flop device with separate data, set and reset inputs and with buffered clock. 74ALVCH162721DLG4 is widely used in many applications. First, in the sampling circuit of analog to digital converter and digital to analog converter, it can be used as the sampling flip-flop for the converter circuit. Second, it can also be used to store the input data if it is in the Industrial level digital circuit or in the data acquisition circuit with large input impedance. Third, it can be used to control the timing of digital circuit or control the changing speed of circuit. Fourth, it also can be used for intelligent instrument or digital logic control device.

Working Principle of 74ALVCH162721DLG4

The 74ALVCH162721DLG4 is a two-input flip-flop with dual edge-triggered capabilities and separate data, set, and reset inputs. First, the trigger of the flip-flop is the edge of clock signal. Under the condition that the clock is enable, the falling edge and the rising edge of the clock will be used as the trigger of the flip-flop.Then, the other two inputs of the flip-flop is the data input terminal and reset input terminal. In the working process of flip-flop, the data terminal can input the high or low level after the rising edge of clock. At this time, you can use the reset terminal to control the flip-flop initialization and the data can be stored in the flip-flop. Even if the clock leading edge and the back edge appears or disappears, the data of flip-flop can still maintain the high and low level.

Conclusion

The 74ALVCH162721DLG4 is a kind of dual edge-triggered flip-flop device, which plays an important role in sampling circuit of analog to digital converter, data storage, data acquisition circuit, intelligent instrument, digital logic control device and other circuits. Its working process is that the data signal enters the flip-flop after the rising edge of the clock signal and is controlled by the reset terminal. Finally, the data signal can still maintain a high or low level after the clock\'s leading and trailing edges appear or disappear.
