74LVC126APW-Q100J

Overview

The Nexperia 74LVC126APW-Q100J is a quad buffer and line driver featuring three-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 5 V tolerant inputs and outputs, facilitating translation between mixed 3.3 V and 5 V logic environments. The device incorporates Schmitt-trigger action at all inputs for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down states. Qualified to AEC-Q100 Grade 1 standards, it functions reliably from -40 °C to +125 °C.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• IOFF circuitry prevents damaging backflow current when powered down
• Schmitt-trigger inputs provide tolerance for slower rise and fall times
• 5 V tolerant inputs and outputs enable direct interfacing with 5 V logic

Applications

• Mixed voltage level translation between 3.3 V and 5 V domains
• Partial power-down applications requiring isolation
• Automotive electronic systems

Procurement Notes

Verify the specific suffix 'Q100J' against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the ordering code matches the required TSSOP14 configuration. Confirm compliance with RoHS and REACH regulations relevant to your region before finalizing procurement.

Selection Notes

Select this component when automotive-grade reliability is required alongside 5 V tolerance in low-voltage CMOS designs. The inclusion of IOFF functionality makes it suitable for systems experiencing partial power-down conditions. Verify that the operating temperature range up to +125 °C meets the environmental requirements of the target application.

Part Context

This part belongs to the Nexperia 74LVC126A-Q100 family of quad buffers. It shares functional characteristics with other members like the SO14 variant but utilizes the TSSOP14 package. The Q100 designation indicates adherence to automotive quality standards, distinguishing it from standard commercial logic devices.

Replacement Considerations

The datasheet lists the 74LVC126AD-Q100 as an alternative package option within the same family.
