74AHCT1G02GW,165

Overview

The Nexperia 74AHCT1G02GW,165 is a single 2-input NOR gate housed in a TSSOP5 (SOT353-1) plastic thin shrink small outline package with 5 leads and a body width of 1.25 mm. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, CMOS low power dissipation, and balanced propagation delays. Static characteristics include input leakage current maximums of 2.0 μA at extreme temperatures and supply current maximums of 40 μA at 5.5 V.

Feature Summary

• Provides a single 2-input NOR logic function with TTL-compatible input switching levels
• Features overvoltage tolerant inputs allowing safe interfacing in mixed voltage environments
• Offers high noise immunity and symmetrical output impedance for reliable signal integrity

Applications

• Translators in mixed voltage digital environments
• General purpose logic applications requiring NOR functionality
• Portable and battery-powered equipment due to low power consumption

Selection Notes

Select this component when a single 2-input NOR gate is required with TTL-level input compatibility. The AHCT variant ensures direct interface with standard TTL logic outputs without level shifting. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage constraint and verify that the TSSOP5 package dimensions fit the available PCB footprint.

Part Context

This part belongs to the Nexperia 74AHC/AHCT1Gxx series of single-gate logic devices. These components are designed for space-constrained applications, offering multiple package options including TSSOP5, SC-74A, and XSON5. The series maintains pin compatibility across variants while providing high-speed performance and robust ESD protection compliant with JEDEC standards.

Replacement Considerations

The 74AHC1G02GW serves as the CMOS-level compatible alternative within the same package. Other single NOR gates in the 74AHC1G02 family may be considered if different package types like SC-74A or XSON5 are preferred.
