74HC1G02GW,125

Overview

The Nexperia 74HC1G02GW,125 is a single 2-input NOR gate manufactured using CMOS technology. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features inputs with clamp diodes for interfacing with voltages exceeding VCC. Static characteristics include high-level input voltage thresholds up to 4.2 V at 6.0 V supply and low-level output voltage as low as 0.33 V at 2.6 mA load. Dynamic performance specifies propagation delays ranging from 8 ns to 23 ns depending on supply voltage and load capacitance.

Feature Summary

• CMOS low power dissipation with symmetrical output impedance
• High noise immunity and balanced propagation delays
• Input clamp diodes enable current limiting resistor usage for over-voltage interfacing

Applications

• General-purpose logic signal processing
• Interface circuits requiring voltage level translation via current limiting resistors
• Digital systems operating in wide temperature environments

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the GW suffix denotes the SOT353-1 (TSSOP5) plastic thin shrink small outline package. Confirm that the application environment remains within the specified -40 °C to +125 °C operating temperature range. Ensure supply voltage constraints between 2.0 V and 6.0 V are strictly adhered to during design integration.

Selection Notes

Select this component when a single 2-input NOR function is required in a compact surface-mount form factor. The HC series offers standard CMOS input levels suitable for general digital applications. Consider the HCT variant if TTL input levels are necessary instead of CMOS levels. Verify that the TSSOP5 package dimensions align with the PCB footprint requirements.

Part Context

This component belongs to the Nexperia 74HC/HCT1Gxx family of single-function logic gates. These devices are designed for space-constrained applications requiring minimal component count. The 74HC1G02 specifically provides NOR logic functionality, distinguishing it from AND or NAND variants within the same package lineup.

Replacement Considerations

The 74HCT1G02GW,125 serves as a functional replacement with identical pinout but different input voltage thresholds. Other single 2-input NOR gates in the 74HC1Gxx series may be considered if package compatibility allows.
