Functional Features

  • Transparent Latch: Allows data to pass through when the latch enable (LE) input is high.
  • 3-State Outputs: The outputs can be put into a high-impedance state using the output enable (OE) input.
  • Edge-Triggered Flip-Flops: The latch captures data on the rising edge of the clock (CLK) input.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer. - Low-voltage operation reduces power consumption. - 3-state outputs provide flexibility in connecting multiple devices.

Disadvantages: - Limited voltage range (2.7V to 3.6V) may not be suitable for all applications. - TSSOP package may require careful handling during assembly.

Working Principles

The 74LVTH322373G is designed to store and transfer data using transparent latches and flip-flops. When the latch enable (LE) input is high, the data inputs (D0-D31) are passed through to the corresponding data outputs (Q0-Q23). The latch captures the data on the rising edge of the clock (CLK) input. The output enable (OE) input can be used to put the outputs into a high-impedance state, allowing multiple devices to share the same bus.

Detailed Application Field Plans

The 74LVTH322373G is commonly used in various applications that require high-speed data storage and transfer. Some potential application fields include:

  1. Communication Systems: Used for buffering and routing data between different communication modules.
