74LVC126ADB,112

Overview

The Nexperia 74LVC126ADB,112 is a quad buffer and line driver featuring three-state outputs within the LVC logic family. It operates on a supply voltage range of 1.2 V to 3.6 V and utilizes a TSSOP-14 package. The device provides four non-inverting buffers with output enable inputs (nOE) that control the high-impedance OFF-state. It supports an operating temperature range from -40 °C to +125 °C and includes overvoltage tolerant inputs for mixed-voltage applications.

Feature Summary

• Quad non-inverting buffer configuration with three-state outputs controlled by active-low enable signals
• Wide supply voltage compatibility ranging from 1.2 V to 3.6 V for low-power operation
• Overvoltage tolerant inputs allowing direct interfacing in mixed-voltage environments
• High noise immunity with balanced propagation delays across all channels

Applications

• Bus-oriented memory and register interfaces requiring tri-state control
• Clock distribution circuits in low-voltage digital systems
• Data bus drivers for portable and battery-powered devices
• Mixed-signal translation between different voltage domains

Procurement Notes

Verify the specific ordering code 74LVC126ADB,112 against official Nexperia documentation to confirm the TSSOP-14 package variant. Ensure design compliance with the specified 1.2 V to 3.6 V supply limits and -40 °C to +125 °C temperature ratings. Confirm RoHS and REACH status through current manufacturer declarations prior to integration.

Selection Notes

Select this component when a quad buffer with three-state capability is required in a compact surface-mount package. The LVC series offers superior speed-to-power performance compared to older standards. Verify input voltage tolerance matches the source logic levels and ensure the load capacitance requirements align with the desired switching speeds for the target application.

Part Context

This part belongs to the 74LVC126A family of quad buffers with 3-state outputs manufactured by Nexperia. It is designed for low-voltage CMOS applications and serves as a standard interface solution for digital signal routing. The device complements other logic families by providing reliable buffering with minimal power consumption in modern electronic designs.

Replacement Considerations

Compatible substitutes include the 74LVC126AD,118 and 74LVC126APW,118. These alternatives maintain identical logical functionality and pinout configurations while potentially differing in packaging or reel specifications. Verify electrical parameters and thermal characteristics before substitution.
