SN74AHC1G02DBVRG4

Overview

The SN74AHC1G02DBVRG4 is a single-channel, 2-input positive NOR gate from Texas Instruments' AHC logic family. It operates within a supply voltage range of 2 V to 5.5 V and features Schmitt-trigger inputs for noise tolerance. The device provides an output drive capability of ±8 mA at 5 V and exhibits a maximum propagation delay of 6.5 ns at 5 V. It is housed in a SOT-23-5 surface-mount package and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Implements Boolean NOR logic function with Schmitt-trigger action on all inputs to tolerate slow rise and fall times.
• Delivers high-speed performance with low propagation delay across the specified voltage range.
• Provides robust output drive strength suitable for driving moderate capacitive loads.

Applications

• Portable consumer electronics requiring minimal board space
• Battery-powered systems utilizing wide voltage operation
• Signal conditioning for noisy digital environments

Procurement Notes

Verify the complete part number including the G4 suffix, which indicates lead-free and RoHS compliance. Confirm the package type is SOT-23-5 and ensure the logic function matches the required NOR gate application. Check datasheet specifications for electrical characteristics relevant to the specific operating voltage and temperature conditions.

Selection Notes

Select this component when a single 2-input NOR gate is needed in a compact footprint. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Ensure the input signals are compatible with the Schmitt trigger thresholds and that the output current requirements do not exceed the specified limits.

Part Context

This device belongs to the SN74AHC1Gxx series of single-gate logic ICs designed for space-constrained applications. The AHC (Advanced High-Speed CMOS) technology combines the speed of ALVC with the low power consumption of standard CMOS. The DBVR suffix specifically denotes the SOT-23-5 package variant manufactured by Texas Instruments.

Replacement Considerations

SN74AHC1G02DBVT: Same logic function and package but different tape-and-reel quantity or handling specification.

FAQ

What is the logic function of the SN74AHC1G02?

It performs a 2-input positive NOR logic function, where the output is high only when both inputs are low.

Does this device have Schmitt trigger inputs?

Yes, all inputs feature Schmitt trigger action, which helps eliminate noise and allows for slower input transition times.
