Product Overview: SN74ABT2244A Octal Buffer/Line Driver

The SN74ABT2244A from Texas Instruments is a high-performance, octal buffer and line driver designed to meet the requirements of high-speed memory address drivers, clock drivers, and bus-oriented receivers and transmitters. This integrated circuit is a part of the ABT family, which is known for its advanced BiCMOS technology, offering both high speed and low power consumption.

Key Features

• High-Speed Operation: The SN74ABT2244A is optimized for operating at high speeds, making it suitable for handling fast signal transitions and improving overall system performance.
• BiCMOS Technology: Incorporating BiCMOS technology allows this device to have the best of both worlds – the low power dissipation of CMOS and the high-speed capabilities of bipolar transistors.
• Drive Capability: It features a ±12-mA output drive at 5 V, which is ideal for driving high capacitive loads and ensures robust signal integrity.
• 3-State Outputs: The octal buffer has 3-state outputs that can be placed in a high-impedance state, effectively disconnecting them from the bus or transmission line. This is particularly useful in bus-oriented systems.
• Input and Output Gating: The G (Output Enable) and DIR (Direction) inputs control the data flow. The G input must be low to enable the outputs, whereas the DIR input determines the direction of data flow through the buffer.

Applications

The versatility of the SN74ABT2244A makes it suitable for a wide range of applications, including:

• Memory address driving
• Bus transceivers in high-speed systems
• Backplane driving
• Clock distribution networks

Package and Quality

The SN74ABT2244A is offered in a variety of packages, including the space-saving SSOP (Shrink Small-Outline Package) and the standard TSSOP (Thin Shrink Small-Outline Package). Texas Instruments is committed to high-quality standards and ensures that this product is compliant with the RoHS directive, making it suitable for use in environmentally sensitive applications.
