Functional Features

• Transparent latch operation
• Non-inverting outputs
• High-speed data transfer
• Low power consumption
• Wide operating voltage range
• Schmitt-trigger inputs for noise immunity

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer. - Low-voltage operation reduces power consumption. - Transparent latch enables real-time data storage and retrieval. - Schmitt-trigger inputs provide noise immunity.

Disadvantages: - Limited number of data inputs and outputs (8 each). - Propagation delay may affect timing-sensitive applications. - TSSOP package may require careful handling during assembly.

Working Principles

The 74LVQ373TTR is a transparent latch that stores and transfers data. When the latch enable (LE) pin 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; when OE is high, the outputs are in a high-impedance state.
