Working Principles

The 74LCX273FT(AJ) is a positive-edge triggered D-type flip-flop with master reset functionality. It stores and transfers data based on the clock pulse input (CP). The flip-flop outputs (Q0-Q7) reflect the state of the data inputs (D0-D7) at the rising edge of the clock signal.

The master reset input (MR) allows synchronous reset of all flip-flops when activated. The output enable input (OE) controls the tri-state outputs, enabling or disabling their connection to the bus.

Detailed Application Field Plans

The 74LCX273FT(AJ) is commonly used in various digital systems and applications, including:

1. Microprocessors and microcontrollers
2. Data storage and retrieval systems
3. Communication devices (routers, switches)
4. Industrial control systems
5. Automotive electronics
6. Consumer electronics (TVs, set-top boxes)
