Working Principles

The MC74LVX74DTR2G operates as a dual D-type flip-flop. Each flip-flop has two inputs: a data input (D) and a clock input (CLK). The outputs (Q and /Q) store the state of the inputs based on the clock signal. The set (/PR) and reset (/CLR) inputs allow for asynchronous control of the flip-flop states.

When the clock signal transitions from low to high, the data input is transferred to the output. The set and reset inputs override the clock input, forcing the outputs to specific states regardless of the clock signal.

Detailed Application Field Plans

The MC74LVX74DTR2G can be used in various digital systems that require data storage and transfer. Some potential application fields include:

1. Microcontrollers: Used to store and synchronize data between different components of a microcontroller.
2. Communication Systems: Employed in data transmission circuits to ensure accurate and synchronized data transfer.
3. Digital Displays: Utilized to control the display of information in devices such as digital clocks or electronic signage.
4. Memory Modules: Integrated into memory modules to store temporary data during read and write operations.
5. Automotive Electronics: Incorporated in automotive systems for tasks like controlling lights, sensors, or motor drivers.
