74AHCT2G126DP-Q10H

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT2G126DP-Q10H is a dual buffer and line driver featuring three-state outputs controlled by active-high output enable inputs (nOE). It belongs to the AHCT logic family, utilizing TTL input switching levels while supporting a wide supply voltage range from 2.0 V to 5.5 V. The device incorporates overvoltage tolerant inputs capable of withstanding up to 5.5 V, facilitating translation in mixed-voltage environments. Qualified to AEC-Q100 Grade 1 standards, it operates reliably across an extended temperature range from -40 °C to +125 °C.

• Mixed voltage signal translation between different logic domains
• Bus-oriented transmission applications utilizing three-state control
• Line driving tasks in automotive communication networks

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'H' against official Nexperia documentation to confirm packaging or tape-and-reel specifications, as datasheets may list base part numbers without this suffix. Confirm the TSSOP8 package type matches design requirements. Ensure the AHCT variant is selected for TTL input compatibility rather than the AHC CMOS version. Cross-reference the marking code C26 on the physical component to validate authenticity and correct revision level.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-level input compatibility is required alongside a wide supply voltage range. The AHCT variant differs from the AHC version by accepting TTL input levels, making it suitable for interfacing with legacy 5 V logic sources. Verify that the operating temperature range extends to +125 °C to meet automotive environmental constraints. Ensure the three-state functionality aligns with the system's bus architecture requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of Nexperia's 74AHC_AHCT2G126-Q100 series, which includes both AHC and AHCT variants. The series provides dual buffer/line drivers with three-state outputs designed for automotive and industrial applications. The DP suffix indicates the TSSOP8 plastic thin shrink small outline package, offering a compact footprint for space-constrained designs while maintaining electrical performance specified for harsh environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHC2G126DP-Q100 serves as a functional substitute if CMOS input levels are acceptable instead of TTL. The 74AHCT2G126DC-Q100 offers identical electrical characteristics but utilizes a VSSOP8 package, requiring PCB layout adjustments. Verify pinout compatibility and thermal dissipation capabilities when substituting packages.
