74AHCT1G04GW,165

Overview

The Nexperia 74AHCT1G04GW,165 is a single inverter within the 74AHCT logic family. It operates with a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels. The device provides overvoltage tolerant inputs up to 5.5 V, ensuring compatibility in mixed-voltage environments. It utilizes a TSSOP5 (SOT353-1) surface-mount package with five leads. Static characteristics include an input leakage current maximum of 2.0 μA at -40 °C to +125 °C. Dynamic performance specifies a propagation delay of 8.5 ns maximum at 5.0 V with 50 pF load capacitance across the full temperature range.

Feature Summary

• TTL-compatible input switching levels for direct interface with Transistor-Transistor Logic systems
• Overvoltage tolerant inputs allowing safe operation when driven by signals exceeding the supply voltage
• Balanced propagation delays and symmetrical output impedance for consistent signal inversion

Applications

• Signal level translation between TTL sources and CMOS loads
• Digital logic inversion in mixed-voltage circuit architectures
• Buffering and waveform shaping for digital data lines

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and tape-and-reel specifications. Ensure the procurement channel provides original manufacturer packaging to maintain component integrity. Cross-reference the part number with official Nexperia databases to validate authenticity and traceability before finalizing orders.

Selection Notes

Select this component when TTL input thresholds are required within a 5 V CMOS system. The AHCT variant ensures compatibility with legacy TTL outputs while maintaining CMOS noise immunity. Verify that the operating environment remains within the specified 4.5 V to 5.5 V supply range and that the thermal conditions do not exceed the maximum junction temperature limits defined in the datasheet.

Part Context

This device belongs to the 74AHCT1G04 series of single inverters manufactured by Nexperia. The series is designed for high-speed digital applications requiring low power consumption and robust noise immunity. The GW suffix indicates the TSSOP5 plastic thin shrink small outline package, which is suitable for space-constrained surface-mount designs.

Replacement Considerations

The 74AHCT1G04GV serves as a pin-compatible alternative using the SC-74A package. Designers must verify footprint dimensions and soldering profiles when substituting packages. Electrical characteristics remain identical across package variants within the same logic family.
