Functional Features

  • Transparent latch function: Allows data input to be stored when the latch enable (LE#) input is high.
  • 3-state outputs: Provides a high-impedance state when the output enable (OE#) input is high, allowing multiple devices to share a common bus.

Advantages and Disadvantages

Advantages

  • High-speed operation enables efficient data processing.
  • Low power consumption helps conserve energy.
  • Wide operating voltage range allows for compatibility with various systems.
