SN74AHC04DR

Overview

The SN74AHC04DR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN74AHC series of high-speed CMOS logic devices. It contains six independent inverting gates within a single package. The device operates with a supply voltage range of 2 V to 5.5 V and supports an output drive current of 8 mA for both high and low states. It is housed in a 14-pin SOIC surface-mount package and is rated for operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Contains six independent inverting gates for signal inversion applications
• High-speed CMOS technology ensures fast switching performance
• Wide operating supply voltage range compatible with various logic families
• Extended industrial temperature rating for reliable operation in harsh environments

Applications

• General-purpose digital signal inversion in electronic circuits
• Clock signal generation and conditioning
• Interface between different voltage logic domains
• Signal buffering and waveform shaping

Procurement Notes

Verify the specific suffix DR indicates the 14-SOIC package and tape-and-reel packaging configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the ordering part number matches the required package style and moisture sensitivity level for your assembly process.

Selection Notes

Select this component when six independent inverters are required in a compact surface-mount format. The AHC series offers faster propagation delays compared to standard HC logic while maintaining CMOS power efficiency. Verify that the 2V to 5.5V supply range aligns with your system's power rails and that the 8mA output current meets the load requirements of the driven inputs.

Part Context

This device is part of the broader SN74AHC family of high-speed CMOS logic ICs produced by Texas Instruments. The family includes various gate types such as NAND, NOR, and flip-flops, all sharing similar electrical characteristics and pinout conventions where applicable. The SN74AHC04 specifically provides the inverting function, serving as a fundamental building block for complex digital logic designs.

Replacement Considerations

Compatible substitutes include other hex inverters from the same family, such as the SN74AHC04D (same function, different package) or SN74AHC04PW (TSSOP package). Cross-vendor equivalents like the MC74AHC04 may be considered if pin compatibility and electrical specifications match exactly.
