Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with three-state capability is required for TTL-to-CMOS level interfacing. The AHCT variant ensures compatibility with standard TTL logic levels while providing CMOS drive characteristics. Ensure the design accommodates the XSON6 package footprint and thermal requirements for high-temperature operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC/AHCT 1G series of single-gate logic devices. These components are designed for space-constrained applications requiring minimal board area. The 1G series offers similar functionality to traditional multi-gate packages but in significantly smaller form factors, supporting modern miniaturization trends in electronic design.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other 74AHCT1G126 variants such as 74AHCT1G126GW (TSSOP5) or 74AHCT1G126GV (SC-74A). Verify that the substitute package matches the PCB footprint and thermal dissipation needs of the original design.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the input logic level for the 74AHCT1G126?

The 74AHCT1G126 is designed to accept TTL-level input signals, making it compatible with standard TTL logic families.

How does the output enable (OE) pin function?

When the OE pin is LOW, the output assumes a high-impedance OFF-state. When HIGH, the output follows the input state A.
