Advantages and Disadvantages

Advantages

  • High-speed operation enables efficient data transfer
  • Wide operating voltage range allows for versatile applications
  • Low power consumption reduces energy requirements
  • Schmitt-trigger inputs ensure reliable switching behavior
  • Balanced propagation delays enable synchronized data transmission
  • 3-state outputs facilitate bus-oriented applications
