Overview
The SN74AHC1G02DBVRE4 is a single 2-input NOR gate from the Texas Instruments AHC logic series. It operates within a supply voltage range of 2 V to 5.5 V and features low static power consumption. The device utilizes a SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +125°C. It provides a low-level output current of 8 mA and a high-level output current of -8 mA, with a typical propagation delay of 6.5 ns.
Feature Summary
- Single-channel 2-input NOR logic function
- Wide operating voltage range from 2 V to 5.5 V
- Extended industrial temperature capability up to 125°C
Applications
- Digital signal processing circuits
- Portable battery-powered equipment
- Consumer electronics logic control
- Industrial process control systems
Procurement Notes
Verify the RE4 suffix indicates lead-free and RoHS compliance status per the official datasheet. Confirm the SOT-23-5 package dimensions match your PCB footprint requirements. Ensure the 2 V to 5.5 V supply voltage aligns with your system design. Check that the -40°C to +125°C temperature rating meets your environmental specifications before finalizing procurement.
Selection Notes
Select this component for applications requiring a compact single NOR gate with wide voltage tolerance. The AHC series offers speed comparable to standard CMOS while maintaining lower power consumption. Consider the SOT-23-5 package for space-constrained designs. Verify input compatibility with your logic family voltages across the entire operating range.
Part Context
This part belongs to the SN74AHC1Gxx series of single-function logic gates. It shares the AHC technology platform with other devices like the SN74AHC1GU04DBVR inverter and SN74AHC1G00DCKRE4 NAND gate. All members utilize similar packaging and electrical characteristics tailored for low-power digital applications.
Replacement Considerations
The SN74AHC1G02DBVT serves as a non-compliant alternative without the RE4 designation. Cross-reference with SN74AHC1G02DBVR for identical functionality but different reel specifications. Verify pinout compatibility when substituting with other single 2-input NOR gates from the same manufacturer.
