SN74AHC1G09DCKR

Overview

The SN74AHC1G09DCKR is a single 2-input positive AND gate from Texas Instruments, belonging to the AHC logic series. It operates within a supply voltage range of 2 V to 5.5 V and features low quiescent current of 1 µA maximum. The device provides ±8 mA output drive capability and exhibits a propagation delay of 7.5 ns at 5 V with 50 pF load. It utilizes an SC-70-5 (SOT-753) surface-mount package and supports an operating temperature range from -55 °C to +125 °C.

Feature Summary

• Executes Boolean AND function Y=A·B in positive logic
• Features open-drain output configuration
• Supports wide supply voltage operation from 2 V to 5.5 V
• Provides high noise immunity typical of advanced CMOS technology

Applications

• Consumer electronics logic control
• Computer peripheral interface circuits
• Embedded system input gating
• Portable battery-powered devices

Procurement Notes

Verify the specific suffix DCKR corresponds to the SC-70-5 tape-and-reel packaging format. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the ordering part number matches the required open-drain variant, as standard push-pull outputs exist in the same family. Cross-reference the datasheet revision date to ensure alignment with current design specifications.

Selection Notes

Select this component when a compact single-gate solution with open-drain output is required for low-voltage digital logic applications. The AHC series offers speed comparable to ALVC while maintaining lower power consumption than standard HC devices. Verify that the downstream circuitry can accommodate open-drain requirements, such as pull-up resistors, before finalizing the design.

Part Context

This part belongs to the SN74AHC1Gxx series of single-function gates designed for space-constrained designs. The AHC series represents Texas Instruments' advanced high-speed CMOS technology, providing significant performance improvements over legacy 74HC devices. The SC-70-5 package allows for high-density PCB layouts in portable and mobile applications where board real estate is limited.

Replacement Considerations

Direct substitutes include SN74AHC1G09DBVR (SOT-23-5 package) and SN74AHC1G09DCKT (cut tape). Automotive-grade alternatives are available in the Q1 series, such as SN74AHC1G09QDRQ1. Non-TI equivalents like Nexperia 74AHC1G09GV125 may require pinout verification.
