74LVC2G126GD,125

Overview

The Nexperia 74LVC2G126GD,125 is a dual bus buffer and line driver featuring three-state outputs controlled by active-high output enable inputs (nOE). It operates within a supply voltage range of 1.65 V to 5.5 V and includes Schmitt-trigger inputs for noise immunity. The device incorporates IOFF circuitry to prevent backflow current during partial power-down states. Inputs are overvoltage tolerant up to 5.5 V, allowing direct interfacing with 3.3 V or 5 V devices. It provides ±24 mA output drive at 3.0 V and complies with JEDEC standards.

Feature Summary

• Dual buffer/line driver with three-state outputs controlled by nOE inputs
• IOFF circuitry prevents damaging backflow current during partial power-down
• Schmitt-trigger action ensures tolerance for slow input rise and fall times
• Overvoltage tolerant inputs allow use as translators in mixed voltage environments

Applications

• Partial power-down applications requiring isolation of powered-down sections
• Mixed voltage translation between 3.3 V and 5 V logic domains
• Bus buffering and line driving in high-noise industrial environments

Procurement Notes

Verify the specific package suffix GD corresponds to the required XSON8 footprint and pinout configuration before ordering. Confirm that the manufacturing date code meets project requirements, as component availability may vary across distributors. Ensure compliance with RoHS3 specifications if applicable to your assembly process. Cross-reference the ordering information table in the datasheet to validate the exact part designation against your bill of materials.

Selection Notes

Select this component when a dual-channel buffer with three-state control is required for low-voltage logic systems. The inclusion of IOFF circuitry makes it suitable for designs where parts of the system must be powered down while others remain active. Verify that the operating temperature range of -40 °C to +125 °C aligns with your environmental constraints. Consider the package dimensions if space is limited on the printed circuit board.
