74AHCT1G02DBVRG4

Overview

The SN74AHCT1G02DBVRG4 is a single 2-input positive-NOR gate from Texas Instruments, part of the AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40°C to 85°C. The device is housed in a 5-pin SOT-23 package with a propagation delay of 7.5 ns at 5 V. It features high-level output current of -8 mA and low-level output current of 8 mA, with a static current of 1 uA.

Feature Summary

• Single-channel 2-input positive-NOR logic function
• Compatible with CMOS outputs and TTL inputs
• Operates at standard 5-V supply voltage

Applications

• Digital signal processing systems
• Consumer electronics logic control
• Industrial control system interfaces

Procurement Notes

Verify the complete part number including the G4 suffix for RoHS compliance status. Confirm the SOT-23-5 package type matches your PCB footprint requirements. Ensure the 4.5 V to 5.5 V operating voltage aligns with your system power rails. Check the -40°C to 85°C industrial temperature rating against environmental conditions.

Selection Notes

Select this component when a single NOR gate is required in a compact surface-mount design. The AHCT series ensures compatibility with existing TTL-based designs while offering CMOS performance. The SOT-23 package is suitable for space-constrained applications. Verify that the 5.5 V maximum supply voltage meets your circuit specifications.

Part Context

This device belongs to the Texas Instruments 74AHCT1Gxx series of single-gate logic ICs. These components are designed for high-speed digital applications requiring small form factors. The AHCT family bridges the gap between older TTL standards and modern CMOS technology, providing robust performance in mixed-voltage environments.

Replacement Considerations

SN74AHCT1G02DBVT: Same logical function and pinout in the same SOT-23-5 package without the G4 suffix.
