Working Principles

The SN74ALVCH374DW is a positive-edge-triggered flip-flop. It stores data on the rising edge of the clock pulse (CP) input. The stored data is then available at the corresponding output pins (Q0-Q7). The Output Enable (OE) pin controls the state of the outputs. When OE is low, the outputs are enabled and reflect the stored data. When OE is high, the outputs are in a high-impedance state.

Detailed Application Field Plans

The SN74ALVCH374DW can be used in various applications, including: - Microprocessor systems - Data storage systems - Communication equipment - Industrial control systems - Automotive electronics
