74AHCT1G02DCKRE4

Overview

The SN74AHCT1G02DCKRE4 is a single 2-input positive-NOR gate manufactured by Texas Instruments. It operates within the AHCT logic series, designed for compatibility with CMOS devices while accepting standard TTL-driven inputs. The device is housed in a SC70-5 surface-mount package and supports a supply voltage range of 4.5 V to 5.5 V. It functions reliably across an extended temperature range from -40°C to +125°C. The component features low input capacitance and is optimized for high-speed digital applications requiring minimal power consumption.

Feature Summary

• Provides a single 2-input NOR logic function in a compact footprint
• Ensures TTL-compatible input levels for seamless integration with legacy systems
• Supports operation at supply voltages up to 5.5 V for robust signal integrity

Applications

• Digital signal processing circuits requiring NOR logic operations
• Consumer electronics utilizing CMOS technology with TTL interfaces
• Portable devices where space constraints necessitate small-scale integration packages

Procurement Notes

Verify the complete part number including the RE4 suffix to ensure correct tape-and-reel packaging configuration. Confirm that the SC70-5 package dimensions align with your PCB layout requirements. Check for RoHS compliance status as indicated in official documentation before finalizing procurement orders.

Selection Notes

Select this component when a single NOR gate is required in a 5-pin surface-mount package. Ensure the system operates within the specified 4.5 V to 5.5 V voltage range. Consider the AHCT series characteristics for TTL-to-CMOS interface compatibility rather than standard AHC performance metrics.

Part Context

This device belongs to the Texas Instruments SN74AHCT1Gxx family of single-gate integrated circuits. The family offers various logic functions such as NAND, NOR, and XOR in ultra-small packages. These components are designed for portable applications and high-density board layouts, providing efficient logic solutions with low power consumption.

Replacement Considerations

Direct substitutes include other variants within the SN74AHCT1Gxx series with identical pinouts. Verify functional equivalence for specific logic gates. Cross-reference package markings to ensure compatibility with existing assembly processes.
