Product Overview: SN74ABT244ADBRG4

The SN74ABT244ADBRG4 is a high-performance, octal buffer/line driver designed by Texas Instruments to meet the needs of modern digital systems. This integrated circuit is part of the ABT family and is characterized by its bidirectional transceiver functionality, making it ideal for driving bus lines or buffer memory address registers.

With its two independent line drivers with 3-state outputs, the SN74ABT244ADBRG4 can be used in situations where output enable signals are required. This feature allows for the connection of multiple outputs to a bus, which can be controlled without the risk of data collision.

Key Features

• Octal Bus Interface: 8-bit wide, making it suitable for bus-oriented applications.
• 3-State Outputs: The outputs can be put in a high impedance state, allowing for bus-sharing scenarios.
• High-Drive Outputs: -32 mA IOH and 64 mA IOL, providing high-current drive capability for heavy loads.
• Wide Operating Voltage Range: Compatible with 4.5V to 5.5V, making it versatile for various logic level systems.
• Low Power Consumption: ICC is reduced by 50%, contributing to energy-efficient designs.
• Edge-Rate Control Circuitry: Minimizes output overshoot and undershoot, enhancing signal integrity.
• Latch-Up Performance: Exceeds 250 mA per JESD 17, ensuring robust operation in adverse conditions.
