74AHC2G126DP-Q100H

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC2G126DP-Q100H is an automotive-grade dual buffer and line driver featuring three-state outputs controlled by active-high output enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device utilizes a TSSOP8 plastic thin shrink small outline package (SOT505-2) with eight leads. Inputs are overvoltage tolerant up to 5.5 V, enabling use in mixed-voltage environments.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1 standards
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• High noise immunity with balanced propagation delays and symmetrical output impedance

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring qualified logic buffers
• Mixed voltage signal translation between different logic domains
• Line driving applications requiring high noise immunity

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DP-Q100H corresponds to the TSSOP8 package and Grade 1 automotive qualification. Confirm that the ordering information matches the required temperature range and package dimensions. Ensure compatibility with existing PCB footprints for SOT505-2 packages during procurement planning.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when automotive reliability under AEC-Q100 Grade 1 is mandatory. Choose this part for designs requiring input tolerance exceeding the supply voltage. Consider the TSSOP8 package constraints and thermal derating characteristics for power dissipation calculations in confined spaces.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Nexperia 74AHC2G126-Q100 family of dual buffers. It shares functional similarities with other automotive-qualified logic devices but is distinct due to its specific three-state control and overvoltage tolerant input architecture designed for robust signal integrity in demanding environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT2G126DP-Q100H serves as a compatible alternative with TTL input levels instead of CMOS levels. Verify pinout compatibility and electrical parameter alignment before substitution.
