74AHCT1G125GM,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT1G125GM,115 is a single bus buffer and line driver featuring a three-state output, housed in an XSON6 (SOT886) package. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level inputs. The device provides high noise immunity and overvoltage tolerant inputs up to 5.5 V. Static characteristics specify a maximum input leakage current of 2.0 μA at -40 °C to +125 °C. Dynamic performance includes a typical propagation delay of 5.5 ns at 5.0 V with 15 pF load capacitance.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing TTL logic sources with CMOS destinations requiring level translation. The AHCT series ensures compatibility with standard TTL input thresholds. Ensure the design accommodates the 4.5 V minimum supply requirement. Consider the XSON6 package dimensions for PCB layout constraints compared to traditional leaded packages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHCT1G125 family of single-buffer line drivers. It shares functional similarities with the 74AHC1G125 but differs in input threshold levels, specifically supporting TTL logic inputs. The GM suffix denotes the XSON6 package variant, distinguishing it from TSSOP5 or SC-74A alternatives within the same logical family.
