Product Overview: 74LVT244BDB from NXP Semiconductors

The 74LVT244BDB is a high-performance, low-voltage, BiCMOS technology octal buffer/line driver designed by NXP Semiconductors. This versatile integrated circuit is crafted to meet the requirements of high-speed data transmission while maintaining low power consumption. It is particularly suitable for driving bus lines or buffer memory address registers in a wide array of applications ranging from personal computers to high-speed communication systems.

Featuring eight non-inverting buffers with 3-state outputs, the 74LVT244BDB is capable of driving heavily loaded bus lines with the utmost efficiency. Each output can sink up to 64 mA and source up to 32 mA, providing excellent signal integrity. The 3-state outputs allow connection to a bus-oriented system, effectively preventing bus contention during inactive periods.

Key Features:

• Power Supply: Operates at a nominal voltage of 3.3V, which is ideal for interfacing with low-voltage systems, and is compatible with 5V input levels to ensure ease of use in mixed-voltage environments.
• High-Speed Performance: Offers a typical propagation delay of 3.7ns, ensuring high-speed data transfer for time-sensitive applications.
• Low Power Dissipation: Its BiCMOS technology significantly reduces power consumption without sacrificing speed, making it an eco-friendly choice for power-sensitive designs.
• Bus-Hold Data Inputs: Eliminates the need for external pull-up resistors, thereby simplifying board design and reducing overall component count.
• 3-State Outputs: Facilitates bus management by enabling multiple devices to share a common data bus without the risk of damaging contention.
• High Drive Capability: Can drive up to 64 mA on the output, providing robust signaling in the presence of heavy loads.
