74AHC1G02GW,125

Overview

The Nexperia 74AHC1G02GW,125 is a single 2-input NOR gate in the AHC/VHC/H/U/V series. It operates on a supply voltage range of 2.0 V to 5.5 V with CMOS input switching levels. The device features overvoltage tolerant inputs up to 5.5 V and high noise immunity. It utilizes a TSSOP5 plastic thin shrink small outline package (SOT353-1) with five leads and a body width of 1.25 mm. The component supports an ambient temperature range from -40 °C to +125 °C.

Feature Summary

• Overvoltage tolerant inputs allow operation in mixed voltage environments
• High noise immunity and balanced propagation delays
• CMOS low power dissipation characteristics

Applications

• Mixed voltage translation applications
• General purpose logic circuits
• Signal processing systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and marking code. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure design compliance with absolute maximum ratings for supply voltage and input clamping currents to prevent permanent damage.

Selection Notes

Select this component when a single 2-input NOR function is required within a compact surface-mount footprint. The wide supply voltage range accommodates various digital logic families. Consider the overvoltage tolerance feature if interfacing with higher voltage signals without additional level shifting components.

Part Context

This part belongs to the Nexperia 74AHC1Gxx family of single-function logic gates. It shares functional similarities with other devices in the series but differs in logic function and pin configuration. The GW suffix specifically denotes the TSSOP5 package variant, distinguishing it from SC-74A or XSON5 options.

Replacement Considerations

The 74AHCT1G02GW serves as a compatible alternative offering TTL input switching levels instead of CMOS levels while maintaining the same package and general functionality.
