74LVC2G125GN,115

Overview

The Nexperia 74LVC2G125GN,115 is a dual bus buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 1.65 V to 5.5 V and supports input voltages up to 5.5 V, enabling direct interfacing with TTL levels in mixed 3.3 V and 5 V environments. The device incorporates Schmitt-trigger action for tolerance to slow input transitions and includes IOFF circuitry to prevent backflow current during partial power-down conditions. Packaged in an XSON8 format (SOT1116) measuring 1.2 mm x 1.0 mm x 0.35 mm, it functions reliably from -40 °C to +125 °C.

Feature Summary

• Provides dual buffering with three-state outputs controlled by active-low enable inputs
• Features IOFF circuitry to disable outputs and prevent damaging backflow current when powered down
• Includes Schmitt-trigger inputs to ensure tolerance against slower input 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 operations

Procurement Notes

Verify the specific ordering suffix GN corresponds to the SOT1116 XSON8 package variant with dimensions 1.2 mm x 1.0 mm x 0.35 mm. Confirm that the required temperature range covers the specified -40 °C to +125 °C operational limits. Ensure design compatibility with the active-low output enable logic and check that the application does not exceed the absolute maximum ratings defined in the product data sheet.

Selection Notes

Select this component when a dual buffer with three-state control is required for signals operating between 1.65 V and 5.5 V. It is suitable for designs needing protection against backflow currents during power-down states via its integrated IOFF feature. Choose this part if space constraints favor the extremely thin XSON8 package over standard leaded packages while maintaining high noise immunity and CMOS low-power consumption characteristics.

Part Context

This device belongs to the 74LVC family of logic ICs, designed for low-voltage CMOS applications. The LVC series typically offers wide supply voltage ranges and high noise immunity. As a dual buffer/line driver, it serves as a fundamental building block for digital signal routing and level shifting in portable and computing electronics where power efficiency and signal integrity are critical.

Replacement Considerations

Other variants within the 74LVC2G125 family include DP (TSSOP8), DC (VSSOP8), GT (XSON8), and GS (XSON8) packages. These share identical electrical specifications but differ in physical footprint and pinout orientation. Verify mechanical compatibility before substituting package types.
