Logic - Flip Flops

Flip-flops are a type of simple digital circuits that can store two-bit binary values, 1s and 0s, which can be used for the control and operation of larger systems or machines.The 74V1G79CTR Flip-flop is an IC that is part of the Advanced High Speed CMOS family of logic devices, produced by Toshiba. The device is an improved version of the older 74V1G74IT, which is also a quad D Flip-flop.

Application field

The 74V1G79CTR IC can be used in a variety of applications involving basic binary data storage, and is most commonly used in computer memory subsystems, digital signal processing and video processing. This type of Flip-flop can also be used in the control of complex systems such as telecommunications networks and factory automation systems.

Working principle

The 74V1G79CTR Flip-flop is a positive-edge triggered device. This means that changes in input signals are only conducted on the positive edge, or rising edge, of the clock signal. When the clock signal changes from low to high, the state of the Flip-flop is changed, and the values of the data inputs determine the state of the signal outputs.

The device has four individual FFlops, each of which is controlled by separate clock signal inputs, D inputs (data) and Q outputs. When the clock signal is in its low state, the device ignores any changes in the data inputs. When the clock signal transitions high, the outputs of the Flip-flop are then determined by the value of the data inputs at that time.

In order to reset the state of an FFlop several Reset inputs are also provided. When a logic high level is applied to any of these inputs, the flip-flop is reset and the output changes to logic low.

Conclusion

The 74V1G79CTR Flip-flop IC is a basic digital circuit used in a broad range of applications that require the storage of binary data. The device is a positive edge-triggered Flip-flop, where any changes in data inputs only take effect when a positive edge of the clock signal is detected. Each Flip-flop can also be reset separately by applying logic high levels to the appropriate reset inputs.
