SN74AUP1G74DCUR Integrated Circuits (ICs)

The SN74AUP1G74DCUR is a dual-input positive-edge triggered D flip-flop with separate D inputs and clock inputs. It is a type of a clocked data storage element with two data inputs, the ‘data’ input and the ‘clock’input. When the clock pin receives a rising edge, the data held at the ‘data’ input will be stored in the output. This can be considered a basic memory element in digital circuits.

Application Field

The SN74AUP1G74DCUR can be used in various circuits as clocked or data storage elements. One of the most common applications can be found in counting or timing circuits. In circuits like these, the flip-flop can be used to store information about a certain count or interval of time. Another use for this flip-flop can be found in asynchronous pulse generators, shift registers, or binary dividers. Other applications may include waveform generation and state machine designs.

Working Principle

The SN74AUP1G74DCUR is a dual-input D flip-flop that is triggered by a positive-edge clock. When the clock signal goes from low to high, the data held at the data input is set and stored at the output. When the clock input is low, the data value at the data input is ignored and the data held at the output remains unchanged. Since the flip-flop is ‘edge’ triggered, it is important to note that if the data at the data input continuously changes while the clock is high, the output will only change with the first full low-high-low transition of the clock.

The SN74AUP1G74DCUR also has two input resets. These are active-low asynchronous inputs that will override the data and clock inputs, resetting the output. It is important to note that the ‘reset’ inputs must remain low for at least the same amount of time as the clock input high time in order to reset the output.

The SN74AUP1G74DCUR is a useful and efficient device for various clocking applications. Its dual data inputs and two reset inputs provide the flexibility to use it in different applications. By understanding the device’s application field and working principle, one can easily make use of the SN74AUP1G74DCUR and its many features in various circuit designs.
