SN74AHC1G08DCKJ

Overview

The SN74AHC1G08DCKJ is a single 2-input positive-AND gate from the Texas Instruments AHC logic family. It operates within a supply voltage range of 2 V to 5.5 V and utilizes SC-70 (SOT-353) surface-mount packaging with five pins. The device provides an output drive capability of ±8 mA at 5 V and exhibits a maximum propagation delay of 7 ns at 5 V. It supports input levels compatible with TTL and CMOS standards, ensuring versatility in mixed-voltage systems while maintaining low power consumption characteristics typical of the AHC series.

Feature Summary

• Executes Boolean AND logic functions for digital signal processing
• Operates across a wide supply voltage range from 2 V to 5.5 V
• Provides robust output drive current capabilities for standard loads
• Compatible with both TTL and CMOS input logic levels

Applications

• Portable battery-powered consumer electronics
• Computing equipment and peripheral interface circuits
• Embedded system logic control and data routing
• Industrial instrumentation signal conditioning

Procurement Notes

Verify the specific suffix 'J' against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SC-70 form factor. Confirm that the operating temperature range meets the design requirements for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when a compact single-gate solution is required for 2-to-5.5 V logic applications. The AHC series offers faster switching speeds compared to standard HC devices while maintaining CMOS low-power advantages. Consider the SC-70 package size constraints and verify that the ±8 mA output drive suffices for the connected load capacitance and fan-out requirements.

Part Context

This part belongs to the SN74AHC1G08 series of single-function gates manufactured by Texas Instruments. The AHC series represents high-speed CMOS technology designed to replace older HC/HCT logic families with improved performance metrics. The DCKJ designation indicates a specific surface-mount package variant within the broader AHC product line, focusing on space-efficient integration for modern electronic designs.

Replacement Considerations

Direct replacements include SN74AHC1G08DCKR or SN74AHC1G08DBVR from Texas Instruments, provided the pinout and electrical characteristics remain identical. Cross-manufacturer equivalents such as those from Diodes Incorporated may require verification of voltage tolerances and package dimensions.
