Product Overview: 74AHC126D by NXP

The 74AHC126D is a high-speed Si-gate CMOS device from NXP Semiconductors, designed to deliver robust performance in a wide range of digital applications. This integrated circuit features quadruple bus buffer gates with 3-state outputs, making it an ideal choice for driving bus lines or buffer memory address registers.

Key Features

• Voltage Range: The device operates on a 2 V to 5.5 V power supply, ensuring compatibility with a variety of logic levels and providing design flexibility across multiple platforms.
• High Noise Immunity: The 74AHC126D comes with an inherent high noise immunity characteristic of the AHC family, making it suitable for noisy environments.
• Low Power Consumption: It boasts low power consumption with a typical I_CC of only 2 μA, providing an energy-efficient solution for power-sensitive designs.
• 3-State Outputs: The quad buffers have 3-state outputs which can be used in bus-oriented systems. The outputs can be put in a high-impedance state, effectively disconnecting them from the bus.

Functional Description

The 74AHC126D has four independent buffer gates, each with a separate input (An) and output (Yn). The 3-state output is controlled by an active HIGH enable input (nOE). When nOE is LOW, the output is active and reflects the input state. When nOE is HIGH, the output assumes a high-impedance state. This feature allows multiple outputs to be connected to a common bus without conflict.

Package and Quality

Encased in a 14-pin SOIC package, the 74AHC126D is designed to occupy minimal board space while providing maximum functionality. It adheres to the stringent quality standards set by NXP, ensuring reliable performance in both commercial and industrial applications.

Applications

With its versatile features, the 74AHC126D is suited for a variety of applications including:

• Buffering and driving bus lines
• Memory address registers
• Control systems
• Data management systems

Overall, the 74AHC126D from NXP is a robust and reliable choice for designers looking for a high-performance bus buffer gate with 3-state outputs.
