74AHCT1G02GW,125

Overview

The Nexperia 74AHCT1G02GW,125 is a single 2-input NOR gate housed in a TSSOP5 (SOT353-1) package. 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 TTL input levels and overvoltage tolerant inputs up to 5.5 V. Static characteristics include a maximum input leakage current of 2.0 μA and a maximum supply current of 40 μA at 5.5 V. Dynamic performance specifies a typical propagation delay of 4.9 ns with a 50 pF load.

Feature Summary

• Overvoltage tolerant inputs allow operation in mixed voltage environments without external protection resistors.
• TTL input switching levels ensure compatibility with standard logic families while maintaining CMOS low power dissipation.
• High noise immunity and symmetrical output impedance provide balanced propagation delays for reliable signal integrity.

Applications

• Translating signals between mixed voltage logic domains
• Implementing basic NOR logic functions in digital circuits
• Signal buffering and routing in high-speed data processing systems

Procurement Notes

Verify the specific ordering suffix 'GW' corresponds to the TSSOP5 plastic thin shrink small outline package with 5 leads. Confirm that the component meets the required automotive or industrial temperature specifications if operating outside standard ranges. Ensure compliance with RoHS directives and check for any specific halogen-free requirements mandated by your assembly process before finalizing procurement orders.

Selection Notes

Select this component when TTL-compatible inputs are required alongside a wide supply voltage capability. The TSSOP5 package offers a compact footprint suitable for space-constrained designs. Consider the overvoltage tolerance feature if interfacing directly with 5.5 V sources without additional level shifting circuitry is necessary for the application architecture.

Part Context

This part belongs to the Nexperia 74AHCT1G series of single-function gates. It shares the same logical function as the 74AHC1G02 but utilizes TTL input thresholds instead of CMOS levels. The GW suffix specifically denotes the SOT353-1 surface-mount package variant, distinguishing it from other package options like SC-74A or XSON5 available within the broader product family.

Replacement Considerations

The 74AHC1G02GW,125 serves as a functional equivalent with CMOS input levels rather than TTL. Verify that the system can tolerate the different input voltage thresholds associated with the AHC series before substituting this AHCT variant.
