Procurement Notes

Verify the complete part number including suffixes such as RE4, which indicates specific manufacturing or compliance attributes. Confirm the package type matches the design footprint requirements. Ensure the voltage supply aligns with the specified 4.5 V to 5.5 V operational range. Check RoHS compliance status if required by environmental regulations. Validate the operating temperature range against the intended application environment.

Selection Notes

Select this component when interfacing between different logic families requiring level shifting. The AHCT series ensures compatibility with both CMOS and TTL standards. Consider the propagation delay and output drive strength for timing-critical applications. Evaluate the package size constraints relative to available board space. Verify thermal performance within the specified industrial temperature limits.

Part Context

This device belongs to the SN74AHCT00 series of single-function gates manufactured by Texas Instruments. It is part of the broader AHCT/VHCT/VT logic family designed for high-speed digital applications. The component serves as a fundamental building block for combinational logic circuits in electronic systems.

Replacement Considerations

SN74AHCT00DRG4 is a verified alternative offering identical logical functionality and electrical specifications. Both variants share the same pinout and package dimensions, facilitating direct substitution in existing designs without circuit modification.
