Working Principles

The 54FCT574TLB operates based on the principles of sequential logic. When the clock pulse (CP) is triggered, the input data (D0-D7) is latched and stored within the flip-flops. The stored data can then be retrieved from the output pins (Q0-Q7). The output enable (OE) pin controls whether the stored data is transmitted to the output pins or not. The asynchronous clear functionality allows for the simultaneous reset of all flip-flops.

Detailed Application Field Plans

The 54FCT574TLB finds applications in various digital electronic systems, including but not limited to: - Microprocessors and microcontrollers - Data storage devices - Communication systems - Industrial automation - Automotive electronics
