74LVC2G126GF,115

Overview

The Nexperia 74LVC2G126GF,115 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 accepts overvoltage tolerant inputs up to 5.5 V. The device incorporates Schmitt-trigger action for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down states. It is housed in an XSON8 package (SOT1089) with dimensions of 1.35 x 1 x 0.5 mm.

Feature Summary

• Dual buffer/line driver with three-state outputs controlled by nOE inputs
• IOFF circuitry enables partial power-down mode operation
• Schmitt-trigger inputs provide tolerance for slow rise and fall times

Applications

• Mixed 3.3 V and 5 V environment translation
• Partial power-down applications requiring backflow prevention
• Bus buffering and line driving in low-voltage systems

Procurement Notes

Verify the specific ordering suffix GF against the manufacturer's latest documentation to confirm the SOT1089 XSON8 package variant. Ensure compatibility with system voltage levels and thermal requirements before finalizing procurement. Cross-reference the part number with official Nexperia distributors to confirm current production status and availability.

Selection Notes

Select this component when a dual buffer with three-state control and partial power-down protection is required. The wide supply voltage range supports various logic families. Verify that the XSON8 package dimensions fit the PCB layout constraints. Confirm that the input voltage tolerances match the source signal levels in the target application.

Part Context

This device belongs to the 74LVC2G126 family of dual bus buffers. The GF suffix specifically denotes the XSON8 package type (SOT1089), which measures 1.35 x 1 x 0.5 mm. Other variants in the series include DP, DC, GT, GN, and GS packages, offering different form factors for diverse mounting needs.

Replacement Considerations

Direct replacements must maintain the dual buffer function, three-state outputs, and XSON8 package. Verify pinout compatibility and electrical specifications such as supply voltage range and drive current. Check for any changes in propagation delay or leakage characteristics that might impact system performance.
