Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the suffix TE4, which indicates tape and reel packaging, against your bill of materials. Confirm that the AHCT series voltage requirements align with your system's 5-V logic interface needs. Ensure the SC-70-5 footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between 3.3-V or lower logic sources and 5-V loads, as the HCT inputs accept standard CMOS levels while driving 5-V outputs. The single-gate configuration minimizes board space compared to quad buffers. Consider the propagation delay and drive current specifications to ensure signal integrity for your specific data rates and load capacitances.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AHCT1Gxx series of single-function logic ICs. These components are designed for low-voltage and mixed-mode circuit applications. The AHCT series bridges the gap between older HC/HCT technologies and newer LVC/AUP families, offering robust performance in 5-V systems while maintaining compatibility with modern low-voltage logic interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AHCT1G125DCKT is the equivalent part without the green (RoHS) suffix. SN74AHC1G125DCKTE4 is similar but uses AHC inputs instead of HCT. SN74LVC1G125DCKTE4 offers wider voltage ranges but different input thresholds.
