74AHCT1G04GW,125

Overview

The Nexperia 74AHCT1G04GW,125 is a single inverter within the 74AHCT logic family. It operates on a supply voltage range of 4.5 V to 5.5 V and utilizes TTL input switching levels. The device features overvoltage tolerant inputs up to 5.5 V, allowing use as translators in mixed-voltage environments. It provides symmetrical output impedance with balanced propagation delays. Static characteristics include an input leakage current maximum of 2.0 μA and a supply current maximum of 40 μA at 5.5 V. Dynamic performance specifies a typical propagation delay of 3.4 ns at 4.5 V to 5.5 V with 15 pF load capacitance.

Feature Summary

• TTL input switching levels for direct compatibility with standard digital logic interfaces
• Overvoltage tolerant inputs enabling safe operation in mixed voltage system architectures
• High noise immunity combined with CMOS low power dissipation characteristics
• ESD protection exceeding 2000 V under Human Body Model testing standards

Applications

• Signal inversion in mixed voltage circuit designs
• Voltage level translation between different logic families
• General purpose digital signal processing applications

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the GW designation corresponds to the TSSOP5 plastic thin shrink small outline package. Confirm that the AHCT series specification aligns with the target application's voltage requirements, specifically the 4.5 V to 5.5 V operating range. Ensure compliance with RoHS directives and check for any specific automotive or industrial qualification requirements if applicable to the end product design.

Selection Notes

Select this component when TTL-compatible input thresholds are required alongside high-speed CMOS performance. The device is suitable for applications needing overvoltage tolerance without external protection components. Consider the TSSOP5 package constraints regarding thermal dissipation and board space. Verify that the supply voltage remains strictly within the 4.5 V to 5.5 V limits to ensure proper logic level recognition and avoid damage.

Part Context

This part belongs to the 74AHCT1G04 series of single inverters manufactured by Nexperia. The series includes variants with different package options such as SC-74A, XSON6, and XSON5. The AHCT designation indicates compatibility with TTL input levels while maintaining CMOS electrical characteristics. This specific model represents the industry-standard logic function packaged in a compact surface-mount format.

Replacement Considerations

Direct replacements include other 74AHCT1G04 variants from Nexperia such as the 74AHCT1G04GV (SC-74A) or 74AHCT1G04GM (XSON6). Cross-manufacturer equivalents must be verified against the specific pinout and electrical specifications to ensure functional compatibility.
