SN74AHCT1G02DCKR

Overview

The SN74AHCT1G02DCKR is a single 2-input positive-NOR gate from the Texas Instruments SN74AHCT1Gxx series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 7.9 ns at 5 V. The device provides an output current capability of -8 mA for high-level and 8 mA for low-level states. It is housed in a compact SC-70-5 surface-mount package and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Single-channel 2-input NOR logic function
• High-speed operation with 7.9 ns propagation delay
• Wide industrial temperature range up to +125 °C

Applications

• Portable battery-powered equipment
• Consumer electronics
• Computing and peripheral devices

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the AHCT logic family compatibility with 5V CMOS systems. Ensure the SC-70-5 footprint matches the design layout. Check RoHS compliance status via official documentation before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring a single NOR gate in a minimal footprint. The AHCT series ensures TTL-compatible inputs while maintaining CMOS performance. Consider the 5.5 V maximum rating for system voltage headroom. Evaluate the 8 mA drive strength against load requirements.

Part Context

This part belongs to the SN74AHCT1Gxx family of single-gate ICs. These components are designed for low-voltage and portable applications. The family includes NAND, NOR, and buffer variants sharing similar electrical characteristics and pinouts.

Replacement Considerations

SN74AHCT1G02DCKT is the tape-and-reel alternative. SN74AHCT1G02DBVR offers a different SOT-353 package option.
