Product Overview: SN74LVC126ADGVR by Texas Instruments

The SN74LVC126ADGVR is a quadruple bus buffer gate with 3-state outputs, designed and manufactured by Texas Instruments (TI), a leader in semiconductor solutions. This integrated circuit (IC) is part of the LVC family, which is characterized by low-voltage CMOS logic operating at a voltage range of 1.65 to 5.5 V. This feature makes it suitable for interfacing with both 3.3V and 5V systems, providing a versatile solution for mixed-voltage applications.

Each of the four independent buffers of the SN74LVC126ADGVR possesses a 3-state output, which means that aside from the typical high and low logic levels, it can also be placed in a high-impedance (Hi-Z) state. This Hi-Z state is particularly useful for creating bus-oriented systems where multiple devices share the same connection lines, as it allows each device to disconnect its output from the bus without affecting the others.

The SN74LVC126ADGVR is housed in a compact 4-mm × 4-mm TVSOP (Thin Shrink Small Outline Package) that is ideal for space-constrained applications. This package type is known for its small footprint and low profile, making it an excellent choice for portable and handheld devices.

Key features of the SN74LVC126ADGVR include:

• Support for 5V tolerant inputs, which facilitates interfacing with legacy 5V logic without the need for additional level shifters.
• Low static power consumption (ICC), which is critical for battery-operated devices.
• High-drive outputs (±24-mA IOH, IOL), enabling the device to drive capacitive loads and ensuring reliable signal transmission even with long traces or in noisy environments.
• Inputs accept voltages up to 5.5V, allowing direct interfacing with high-voltage signals within the specified supply voltage range.
• Output clamping diodes that provide ESD protection, enhancing the robustness of the device in harsh electrical environments.

With its versatile power supply compatibility and robust output drive capabilities, the SN74LVC126ADGVR is suitable for a wide range of applications, including but not limited to: data bus buffering, signal gating, and logic signal driving in consumer electronics, telecommunications, and computing systems.

TI's commitment to quality ensures that the SN74LVC126ADGVR meets the stringent requirements of modern electronic systems, providing designers with a reliable and flexible buffering solution.
