• Latch enable and output enable control signals for data storage and retrieval
• High-speed operation, suitable for time-critical applications
• Low power consumption
• Wide operating voltage range

Advantages and Disadvantages

Advantages

• Provides temporary storage of data in applications requiring latching functionality
• High-speed operation allows for efficient data handling
• 3-state outputs enable easy interfacing with other devices
• Wide operating voltage range provides flexibility in different power supply scenarios
