Working Principles

The SN74LV373APWRG4 operates as an octal transparent D-type latch. It stores and transfers data based on the latch enable (LE) and clock (CLK) signals. When the latch enable input is high, the data at the inputs (D0-D7) is transferred to the outputs (Q0-Q7) on the rising edge of the clock signal. The output enable (OE) input controls the state of the outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The SN74LV373APWRG4 can be used in various applications, including but not limited to: - Microprocessor-based systems - Data storage and transfer systems - Bus-oriented architectures - Communication systems - Industrial automation
