74LVC126AD,118

Overview

The Nexperia 74LVC126AD,118 is a quad buffer and line driver featuring 3-state outputs controlled by active HIGH enable inputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports 5 V tolerant inputs and outputs. The device utilizes Schmitt-trigger action for noise immunity and includes IOFF circuitry for partial power-down protection. Packaged in an SO14 (SOT108-1) plastic small outline package with a body width of 3.9 mm, it functions across temperatures from -40 °C to +125 °C.

Feature Summary

• Provides four non-inverting buffers with 3-state outputs controlled by dedicated enable pins
• Features 5 V tolerant inputs and outputs allowing direct interfacing between 3.3 V and 5 V devices
• Includes IOFF circuitry to prevent damaging backflow current during partial power-down conditions
• Schmitt-trigger inputs ensure tolerance to slow input rise and fall times

Applications

• Mixed 3.3 V and 5 V environments requiring signal translation
• Partial power down applications utilizing IOFF functionality
• High-speed data buffering with 3-state output control

Procurement Notes

Verify the specific ordering suffix ',118' corresponds to the standard tape-and-reel packaging configuration as defined in the manufacturer's documentation. Confirm that the SO14 package variant matches the required PCB footprint dimensions. Ensure compliance with RoHS directives and REACH regulations applicable to your region before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring bidirectional level shifting or buffering between 3.3 V and 5 V logic domains. The 5 V tolerance feature eliminates the need for additional level-shifting components. Consider the SO14 package constraints regarding thermal dissipation and board space availability compared to alternative packages like TSSOP14.

Part Context

This part belongs to the 74LVC126A family of quad buffers with 3-state outputs. The 'AD' designation specifically identifies the SO14 plastic small outline package variant manufactured by Nexperia. It shares functional characteristics with other package options such as TSSOP14 and DHVQFN14 within the same logical series.

Replacement Considerations

The 74LVC126APW,118 serves as a pin-compatible alternative packaged in TSSOP14.
