Product Description

The 74LVT574DB is a powerful solution for digital systems requiring high-speed data storage and bus management. The device features eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The flip-flop state is controlled by the clock (CP) and output enable (OE) inputs. When OE is low, the device presents the stored data on the Q outputs. When OE is high, the outputs are in a high-impedance state, which is essential for bus systems where multiple devices share the same output lines.

One of the key advantages of the 74LVT574DB is its 3.3V operating voltage, which allows for lower power consumption without sacrificing performance. This makes it suitable for battery-operated and power-sensitive applications. Additionally, its 5V tolerant inputs enable seamless integration with older 5V systems, providing a versatile solution for system upgrades and mixed-voltage environments.

Designed in a DB package, the 74LVT574DB is optimized for surface-mount technology, making it ideal for compact and densely populated PCBs. Its robust design ensures reliable operation in a wide range of industrial and commercial applications, including computing, networking, and telecommunications.
