SN74AHC04DG4

Overview

The SN74AHC04DG4 is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN74AHC04 logic family. It features six independent inverters within a single package. The device operates on a supply voltage range of 2 V to 5.5 V and supports CMOS input and output types. It is housed in a 14-pin SOIC surface-mount package. The component functions across an operating temperature range from -40°C to +85°C. Key electrical specifications include a maximum propagation delay of 8 ns at 5 V with a 50 pF load, and output drive currents of ±8 mA for both high and low states.

Feature Summary

• Contains six independent inverting gates for signal inversion applications
• Supports wide supply voltage operation from 2 V to 5.5 V
• Provides robust output drive capability with ±8 mA current ratings
• Compatible with standard CMOS logic input levels

Applications

• General-purpose digital signal inversion
• Clock signal generation and conditioning
• Interface between different logic families
• Pulse waveform shaping

Procurement Notes

Verify the specific ordering suffix 'G4' to confirm lead-free and RoHS compliance status as defined by Texas Instruments. Ensure the package type matches the required 14-SOIC footprint for PCB layout compatibility. Confirm that the industrial temperature grade (-40°C to +85°C) meets the operational requirements of the target environment before finalizing procurement.

Selection Notes

Select this component when a hex inverter configuration is required within a compact SOIC package. It is suitable for designs needing moderate speed performance with an 8 ns propagation delay. Consider this part for applications requiring a wide supply voltage range up to 5.5 V. Verify that the ±8 mA output drive is sufficient for the connected load capacitance and fan-out requirements.

Part Context

This component is part of the SN74AHC04 series, which includes variants with different packaging options such as TSSOP, SSOP, and VQFN. The 'D' suffix indicates the 14-pin SOIC package, while 'G4' denotes environmental compliance. Other related parts in the family include SN74AHC04DBR and SN74AHC04PW, offering alternative form factors for space-constrained or through-hole designs.

Replacement Considerations

Direct pin-compatible substitutes include SN74AHC04DR and SN74AHC04DBR from Texas Instruments. Cross-manufacturer equivalents may include HC or HCT series inverters, though voltage thresholds and speed characteristics should be verified against the original specification.
