74LVC126AD,112

Overview

The Nexperia 74LVC126AD,112 is a quad buffer and line driver featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 1.2V to 3.6V and provides balanced propagation delays. The device includes Schmitt-trigger action on all inputs and accepts voltages higher than VCC, facilitating use in mixed-voltage environments. It is housed in a 14-SOIC package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Non-inverting quad buffer with three-state output control
• Inputs tolerant to voltages exceeding the supply voltage
• Schmitt-trigger action on all input pins

Applications

• Mixed-voltage signal translation between different logic domains
• High-impedance bus driving applications
• Line buffering for digital communication interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging variants such as tape-and-reel options. Review official datasheets for detailed electrical characteristics and thermal management requirements before integration into final designs.

Selection Notes

Select this component when non-inverting buffering with high-impedance states is required. Ensure the application voltage falls within the 1.2V to 3.6V range. Consider the 14-SOIC package constraints for PCB layout. Verify that the input voltage levels do not exceed absolute maximum ratings despite overvoltage tolerance features.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices. It serves as a standard interface solution for connecting components operating at different voltage levels. The 74LVC126 variant specifically provides four independent buffers with enable controls, widely used in portable electronics and industrial control systems requiring reliable signal isolation.

Replacement Considerations

The 74LVC126AD,118 is a documented substitute offering identical functionality in compatible packaging. Verify pinout compatibility and electrical specifications against the original design requirements before substitution.
