SN74AHCU04DBR

Overview

The SN74AHCU04DBR is a hex inverter integrated circuit manufactured by Texas Instruments. It belongs to the AHC (Advanced High-Speed CMOS) logic family and features six independent inverting gates within a single package. The device operates with a supply voltage range of 2 V to 5.5 V, ensuring compatibility with various digital systems. It supports an extended industrial temperature range from -40°C to +125°C. The component utilizes a 14-pin SOIC surface-mount package for efficient board space utilization.

Feature Summary

• Provides six independent inverting logic functions in a compact integrated circuit
• Utilizes Advanced High-Speed CMOS technology for enhanced performance
• Supports wide operating voltage ranges for flexible system integration
• Designed for reliable operation across extended industrial temperature conditions

Applications

• General-purpose signal inversion in digital logic circuits
• Clock signal generation and conditioning
• Data line buffering and level shifting
• Microcontroller interface logic adaptation

Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the desired tape-and-reel packaging configuration and lead time requirements. Confirm that the industrial temperature grade (-40°C to +125°C) meets your application's environmental specifications. Ensure the 14-SOIC footprint matches your PCB design constraints before finalizing procurement decisions.

Selection Notes

Select this component when six independent inverters are required in a single package. The AHC series offers superior speed compared to standard HC logic while maintaining low power consumption. Consider the 2V to 5.5V operating range for compatibility with both 3.3V and 5V systems. Verify thermal management requirements for high-density applications due to the extended temperature rating.

Part Context

This part is part of Texas Instruments' extensive SN74AHC logic family, designed for high-speed digital applications. The 'U' designation indicates it is part of the unbuffered or standard AHC line, distinct from buffered variants. It serves as a fundamental building block for complex digital designs requiring multiple inversion stages without external components.

Replacement Considerations

Compatible substitutes include SN74AHC04D and SN74AHC04DR, which share identical logical functionality and pinout configurations. These alternatives offer equivalent electrical characteristics and package dimensions, allowing for direct replacement in existing designs without schematic modifications.
