Functional Features

The 74LVQ574TTR is a flip-flop-based octal D-type latch with tri-state outputs. It provides the following functional features:

• Data storage: The IC can store data on its eight inputs and retain it until a new input is received.
• Tri-state outputs: The outputs can be enabled or disabled using the output enable (OE) pin, allowing multiple devices to share a common bus without interference.
• High-speed operation: With its low propagation delay, the IC ensures efficient data processing and transmission.

Advantages and Disadvantages

Advantages

• Low-voltage operation makes it suitable for battery-powered devices.
• Tri-state outputs allow for efficient bus sharing.
• High-speed performance enables fast data processing.

Disadvantages

• Limited voltage range of operation (2.5V to 3.6V).
• Not suitable for high-power applications due to limited output current.

Working Principles

The 74LVQ574TTR operates based on flip-flop logic. When the output enable (OE) pin is active, the inputs are latched and stored in the internal memory. The stored data remains unchanged until a new input is received. The tri-state outputs allow the IC to control the flow of data onto a shared bus, preventing conflicts between multiple devices.
