74AHCT1G32GW,165

Overview

The Nexperia 74AHCT1G32GW,165 is a single 2-input OR gate in the 74AHCT logic family. It operates within 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, enabling use as translators in mixed-voltage environments. It utilizes a TSSOP5 (SOT353-1) 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 9.0 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 standard logic families
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• High noise immunity with symmetrical output impedance and balanced propagation delays

Applications

• Signal translation between different voltage domains
• Logic OR operations in digital circuits
• Mixed voltage system interfacing

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and reel specifications. Confirm RoHS compliance status and environmental declarations prior to integration. Ensure design reviews address absolute maximum ratings to prevent device stress. Validate pinout alignment with PCB footprint requirements during layout phases.

Selection Notes

Select this component when TTL-level inputs are required alongside CMOS output drive capabilities. The AHCT variant ensures compatibility with legacy TTL systems while maintaining low power consumption. Verify that the operating voltage remains within the specified 4.5 V to 5.5 V range for optimal performance. Consider the TSSOP5 package constraints for thermal management and board space availability.

Part Context

This part belongs to the Nexperia 74AHC/AHCT single-gate series, designed for high-speed digital applications. The 74AHCT1G32 specifically targets applications requiring TTL input thresholds with CMOS electrical characteristics. It serves as a compact solution for basic logic functions in space-constrained designs.

Replacement Considerations

Direct substitutes include other single 2-input OR gates from the same family such as the 74AHCT1G32GV or 74AHCT1G32GZ, provided the package type matches the design requirements. Cross-family replacements require verification of input/output voltage levels and propagation delays.
