Product Overview: 74ABT2244DB Octal Buffer/Line Driver

The 74ABT2244DB from NXP Semiconductors is a high-performance, octal buffer and line driver designed to provide bidirectional interfacing to bus-oriented systems. The device integrates eight independent non-inverting buffers/drivers with 3-state outputs into a single package, making it ideal for driving bus lines or buffer memory address registers.

Key Features

• High-Speed Performance: The 74ABT2244DB operates at a high speed, with a typical propagation delay time significantly lower than comparable devices, ensuring fast data transfer and improved system performance.
• 3-State Outputs: The octal drivers feature 3-state outputs, which can be placed in a high-impedance state. This feature is crucial for shared data lines, allowing multiple devices to connect to a bus without contention.
• Live Insertion and Extraction: This device supports live insertion and extraction, minimizing the risk of glitches and errors on the data bus when modules are plugged in or removed during normal operation.
• Multiple V_CC and GND Pins: The inclusion of multiple V_CC and GND pins minimizes the inductive effects of device operation on the power supply, ensuring stable and reliable performance.
• Improved Output Drive: The 74ABT2244DB boasts a robust output drive capability, with the ability to source or sink 64 mA at 3.0V, which is ideal for driving heavily loaded outputs with minimal signal degradation.

Applications

The 74ABT2244DB is suitable for various applications that require high-speed data transfer and driving capabilities, such as:

• Bus drivers in computing systems
• Buffering for memory address registers
• Communication systems
• Data acquisition and instrumentation
• High-performance industrial applications
