74LVC126APW,118

Overview

The Nexperia 74LVC126APW,118 is a quad buffer and line driver featuring 3-state outputs controlled by active HIGH output enable inputs (nOE). It operates within a supply voltage range of 1.2 V to 3.6 V and supports overvoltage tolerant inputs up to 5.5 V. The device utilizes Schmitt-trigger action for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down states. Packaged in a TSSOP14 (SOT402-1) format, it functions as a translator in mixed 3.3 V and 5 V environments.

Feature Summary

• Provides four non-inverting buffers with 3-state outputs controlled by dedicated enable pins
• Features overvoltage tolerant inputs capable of accepting voltages up to 5.5 V while operating at lower supply levels
• Incorporates IOFF circuitry to disable outputs and prevent damaging backflow currents when the device is powered down
• Includes Schmitt-trigger action on all inputs to ensure tolerance against slow input rise and fall times

Applications

• Translating signals between mixed 3.3 V and 5 V logic environments
• Partial power-down applications requiring prevention of backflow current
• Driving bus lines with controlled high-impedance OFF-states

Procurement Notes

Verify the specific ordering suffix ',118' corresponds to the TSSOP14 package configuration. Confirm that the required temperature range aligns with the -40 °C to +125 °C specification provided in the product data sheet. Ensure design compatibility with the 5.5 V input tolerance limits before finalizing procurement specifications.

Selection Notes

Select this component when interfacing between different voltage domains, specifically where 5 V tolerant inputs are necessary alongside 3.3 V or lower supply rails. The inclusion of IOFF functionality makes it suitable for systems requiring safe partial power-down modes. Verify that the TSSOP14 package dimensions meet the available board space constraints.

Part Context

This part belongs to the 74LVC126A family of quad buffers with 3-state outputs. The 'PW' designation indicates the TSSOP14 plastic thin shrink small outline package variant. The ',118' suffix identifies the specific reel packaging configuration used by Nexperia for distribution.

Replacement Considerations

The 74LVC126AD,118 serves as a pin-compatible alternative utilizing the SO14 package.
