Working Principles

The MC74LVX74MG is a digital logic IC that consists of two D-type flip-flops. Each flip-flop has an independent set and reset input, allowing individual control. The flip-flops are triggered by positive-edge clock inputs, which latch the data present at the D input. The outputs Q and Q̅ represent the state of each flip-flop.

Detailed Application Field Plans

The MC74LVX74MG is commonly used in various digital systems and applications, including:

1. Microcontrollers and microprocessors
2. Data storage and retrieval systems
3. Communication devices
4. Timing and synchronization circuits
5. Control and automation systems
