Working Principles

The SN74LVC374AQPWRQ1 operates based on the principles of D-type flip-flops. When the clock pulse (CP) is high, the input data (D0-D7) is transferred to the corresponding flip-flop outputs (Q0-Q7). The transparent latch ensures that the outputs reflect the input data as long as the clock pulse remains high. The output enable (OE) pin controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74LVC374AQPWRQ1 is widely used in various digital systems and applications, including but not limited to: - Microcontrollers - Data storage devices - Communication systems - Industrial automation - Automotive electronics
