Working Principles

The SN74LV373APWR operates by storing and controlling data using transparent D-type latches. When the clock input (CLK) is high, the data inputs (D0-D7) are transferred to the corresponding data outputs (Q0-Q7). The output enable (OE) pin controls the state of the outputs. When OE is low, the outputs are active and reflect the stored data. When OE is high, the outputs are in a high-impedance state.

Detailed Application Field Plans

The SN74LV373APWR is commonly used in various electronic systems, including but not limited to: - Microcontrollers - Data buses - Memory systems - Communication interfaces - Industrial control systems
