SN74LVTH126DRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH126DRG4 is a quad bus buffer with 3-state outputs manufactured by Texas Instruments. It operates at a supply voltage of 2.7 V to 3.6 V and supports mixed-mode signal operation, allowing 5-V input and output voltages with 3.3-V VCC. The device features active bus-hold circuitry on data inputs and Ioff support for hot insertion. It is housed in a 14-pin SOIC package (D) and is RoHS compliant.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation with 5-V tolerant inputs and outputs while operating at 3.3-V VCC
• Features active bus-hold circuitry on data inputs to maintain valid logic states without external resistors
• Provides Ioff and power-up 3-state functionality to prevent damaging current backflow during hot insertion

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed-mode signal translation between 5-V and 3.3-V system environments
• Hot-insertion applications requiring controlled power-up and power-down states
• Unregulated battery operation down to 2.7 V

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix 'G4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the package type corresponds to the SOIC-14 (D) variant with tape and reel packaging. Ensure the component matches the specific SN74LVTH126 family specifications for voltage tolerance and bus-hold features.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 5-V logic devices with 3.3-V systems requiring bidirectional or unidirectional buffering. The LVTH series is suitable for applications needing high noise immunity and low power consumption. Consider the SOIC-14 package for surface-mount assembly constraints and verify thermal requirements for the intended operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH126 family of quad bus buffers. It is designed specifically for low-voltage 3.3-V VCC operation but provides TTL interface capabilities to 5-V systems. The device includes independent line drivers with 3-state outputs controlled by an output-enable input.
