SN74LVC2G126YEAR Dual Bus Buffer Gate with 3-State Outputs
The SN74LVC2G126YEAR from Texas Instruments is a high-performance, dual-line buffer gate that features 3-state outputs designed to be employed in a wide range of digital applications. This integrated circuit (IC) is part of the LVC family, which is known for its low-voltage operation and compatibility with mixed-voltage systems. The device is optimized for 1.65V to 5.5V VCC operation, making it suitable for interfacing with both 3.3V and 5V logic levels.
Each buffer of the SN74LVC2G126YEAR is equipped with a separate output-enable (OE) input, which, when high, disables the output stage by placing it in a high-impedance state. This feature allows for the connection of multiple outputs to a common bus line without the risk of bus contention. When OE is low, the respective buffer's output is active and reflects the input data. The 3-state outputs also enable efficient data flow control and support the implementation of multiplexed buses.
The IC's small footprint is provided by the compact 8-pin YEA (DSBGA) package, which is ideal for space-constrained applications. The SN74LVC2G126YEAR is characterized for operation from -40°C to +85°C, ensuring reliable performance across a broad range of temperature conditions.
Key features of the SN74LVC2G126YEAR include:
- Support for 5V tolerant inputs, which facilitates interfacing with legacy logic levels without the need for additional level shifters.
- Low dynamic power consumption, with a balance of high speed and low power that is typical of the LVC family.
- IOFF support, which ensures that the device is disabled during power down to prevent damaging current backflow through the IC.
- ESD protection exceeding JESD 22, ensuring robustness and longevity in harsh electrical environments.
This dual bus buffer gate is an ideal choice for applications that require buffering with 3-state output control, such as bidirectional communication interfaces, memory address drivers, and data transmission lines. Its high drive strength and wide operating voltage range make it a versatile component in modern digital systems.
