Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm the exact tape-and-reel packaging configuration and manufacturing lot details. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability throughout the supply chain.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel non-inverting buffer with three-state control is required for 5 V logic systems. The AHCT variant ensures compatibility with TTL input thresholds while maintaining CMOS performance. Verify that the operating temperature range and package dimensions align with the target PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC(AHCT)1G126 series of single bus buffers. The series offers various package options including XSON and SC-74A formats. The GW suffix specifically designates the TSSOP5 package type, distinguishing it from other physical form factors available within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include the 74AHCT1G126GV (SC-74A package) and the 74AHCT1G126GM (XSON6 package). These alternatives share identical electrical specifications but differ in physical footprint and pinout orientation.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the OE pin?

The OE pin serves as the output enable input. When driven HIGH, the output assumes a high-impedance OFF-state regardless of the data input level.

How does the device handle overvoltage on inputs?

The inputs are overvoltage tolerant up to 5.5 V, allowing the device to interface safely with higher voltage logic lines without damage or incorrect state interpretation.
