SN74AHC14DRG4

Overview

The SN74AHC14DRG4 is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the AHC logic family. It features Schmitt-trigger inputs for noise filtering and operates within a supply voltage range of 2 V to 5.5 V. The device provides six independent inverters in a 14-pin SOIC package with surface-mount installation. Key electrical characteristics include a maximum propagation delay of 6 ns at 5 V and output drive currents of ±8 mA. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Hex Schmitt-trigger inverters provide hysteresis for improved noise immunity
• Wide supply voltage operation supports both 3.3 V and 5 V systems
• High-speed performance with low propagation delays
• Push-pull outputs deliver strong drive capability

Applications

• Signal conditioning and waveform shaping
• Clock signal generation and buffering
• Noise filtering in digital communication lines
• Oscillator circuits requiring precise threshold control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives and check for any recent product change notifications that may affect pinout or electrical parameters before finalizing procurement.

Selection Notes

Select this component when Schmitt-trigger action is required for clean signal transitions in high-speed digital designs. The AHC series offers superior speed compared to standard HC logic while maintaining compatibility with 5 V and 3.3 V power rails. Consider the SOIC-14 package constraints for PCB layout and thermal management requirements.

Part Context

This part belongs to the SN74AHC14 family of hex inverters with Schmitt triggers. It is functionally compatible with other industry-standard 74AHC14 devices but offers Texas Instruments' specific manufacturing quality and reliability standards. The DRG4 suffix indicates a lead-free, green compound SOIC-14 package with tape and reel packaging.

Replacement Considerations

Cross-reference with SN74AHC14DR or SN74AHC14DRE4 for identical functionality. Verify pin compatibility with competitors like NXP or onsemi equivalents such as 74AHC14DTR before substitution.
