74LVC1G126GXH

Overview

The Nexperia 74LVC1G126GXH is a single non-inverting buffer and line driver featuring three-state outputs, housed in an X2SON5 (SOT1226-3) package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports input voltages up to 5.5 V. The device incorporates Schmitt-trigger inputs for noise immunity and IOFF circuitry to prevent backflow current during partial power-down states. It provides ±24 mA output drive capability at 3.0 V and complies with JEDEC standards for various voltage levels.

Feature Summary

• Features three-state outputs for bus-oriented applications
• Includes IOFF circuitry to disable outputs during power-down
• Schmitt-trigger inputs provide tolerance for slow signal transitions
• Inputs are overvoltage tolerant up to the maximum supply voltage

Applications

• Mixed 3.3 V and 5 V system environments
• Partial power-down mode operation
• Bus-oriented communications

Procurement Notes

Verify that the specific ordering suffix matches the required thermal-enhanced X2SON5 package configuration. Confirm compliance with RoHS and REACH regulations as specified in the product data sheet. Ensure design safeguards account for the absolute maximum ratings to prevent permanent damage from stress conditions exceeding the defined limits.

Selection Notes

Select this component when a single-channel non-inverting buffer with high-noise immunity is required. The inclusion of IOFF circuitry makes it suitable for systems requiring partial power-down functionality. Verify that the operating temperature range meets the application requirements, as the device is specified for -40 °C to +125 °C.

Part Context

This part belongs to the 74LVC logic family, designed for low-voltage CMOS applications. The 'GX' designation specifically identifies the X2SON5 plastic thermal-enhanced package. It serves as a fundamental building block for digital signal buffering and level translation in mixed-voltage electronic designs.

Replacement Considerations

The 74LVC1G125GXH is listed as a parameter-equivalent substitute by distributors.
