74AHCT1G125GV,125

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT1G125GV,125 is a single non-inverting bus buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes TTL input switching levels. The device is housed in an SC-74A (SOT753) package with five leads. Inputs are overvoltage tolerant up to 5.5 V, enabling use as translators in mixed-voltage environments. It provides symmetrical output impedance, balanced propagation delays, and high noise immunity.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix GV corresponds to the SC-74A (SOT753) package configuration required for your PCB layout. Confirm that the TTL input logic levels align with your source circuitry, as this variant differs from the AHC series which uses CMOS levels. Ensure operating conditions remain within the specified 4.5 V to 5.5 V supply voltage range to maintain performance specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible inputs are required alongside a wide supply voltage tolerance. The SC-74A package offers a compact surface-mount solution suitable for space-constrained designs. Consider the overvoltage tolerant inputs if interfacing with higher voltage domains without level shifting components. Verify thermal derating requirements if operating near the maximum temperature limits.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHCT1G125 family of single-buffer line drivers. It shares functional characteristics with the 74AHC1G125 but distinguishes itself through TTL input thresholds. The GV suffix specifically denotes the SC-74A plastic surface-mounted package, differentiating it from TSSOP or XSON variants within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHC1G125GV serves as a direct functional substitute if CMOS input levels are acceptable instead of TTL. Other single-buffer three-state devices from the 74AHC/AHCT series may be compatible provided pinouts and package dimensions match.
