Working Principles

The 74F379SJX is a quad D-type flip-flop that operates on positive-edge triggered clock input. The state of each flip-flop is determined by the data inputs (D0-D3) at the rising edge of the clock signal (CLK). The asynchronous clear input (CLR) clears all flip-flops to logic low, while the asynchronous preset input (PR) sets all flip-flops to logic high.

Detailed Application Field Plans

The 74F379SJX IC finds applications in various digital logic circuits, including but not limited to: - Counters and registers - State machines and sequencers - Data storage and retrieval systems - Control units and timing circuits
