SN74AHCT126D Quad Bus Buffer Gate from Texas Instruments

The SN74AHCT126D is a high-performance, quadruple bus buffer gate designed by Texas Instruments to provide high-speed, non-inverting buffer and driver capabilities. This integrated circuit is part of the 'AHCT' family, which signifies the use of advanced high-speed CMOS technology with TTL-compatible inputs.

Key Features:

• Logic Type: The device features four independent non-inverting buffer gates, ensuring versatility in various logic operations.
• Voltage Range: It operates at a wide range of voltages from 4.5V to 5.5V, making it suitable for interfacing with 5V TTL logic levels while maintaining low power consumption.
• Drive Capability: The SN74AHCT126D offers a high drive capability with 8 mA at the outputs, allowing it to drive multiple loads or even longer bus lines effectively.
• 3-State Outputs: Each buffer gate has a 3-state output, enabling the connection of multiple outputs to a common bus without interference, which is controlled by an output-enable (OE) input.
• Speed: The device boasts fast propagation delays and output transition times, which is critical for high-speed applications.

Applications:

The SN74AHCT126D is ideal for a variety of applications, including:

• Bus driver or buffer applications where high speed and low power are necessary.
• Interfacing with 5V systems in mixed 3.3V/5V supply environments.
• Memory address drivers, clock drivers, and bus-oriented transmitters/receivers.

Physical Attributes:

The device is available in a standard 14-pin SOIC (Small Outline Integrated Circuit) package, denoted by the 'D' at the end of its product name. This package is suitable for surface-mount technology (SMT) and is widely used due to its small footprint on PCBs (Printed Circuit Boards).
