SN74AHC14DRE4

Overview

The SN74AHC14DRE4 is a hex Schmitt-trigger inverter manufactured by Texas Instruments, belonging to the AHC logic series. It operates within a supply voltage range of 2 V to 5.5 V and features six independent inverting circuits. The device utilizes a 14-pin SOIC package for surface-mount installation. Key electrical characteristics include an output current capability of 8 mA for both high and low states, with a maximum propagation delay of 12 ns at 5 V with a 50 pF load. It supports an extended operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates six independent Schmitt-trigger inverters for noise filtering and waveform shaping
• Operates across a wide supply voltage range from 2 V to 5.5 V
• Provides robust output drive capability with 8 mA source and sink currents
• Supports high-temperature operation up to 125°C

Applications

• Signal conditioning and noise elimination in digital systems
• Waveform shaping for oscillators and timing circuits
• Interface between microprocessors and peripheral devices
• Clock signal generation and distribution networks

Procurement Notes

Verify the specific ordering suffix 'E4' corresponds to lead-free and RoHS-compliant specifications as defined by Texas Instruments. Confirm that the SOIC-14 package dimensions match your PCB footprint requirements. Ensure the component meets the required industrial temperature grade of -40°C to +125°C for your application environment. Cross-reference the manufacturer part number with official distributors to ensure authenticity and traceability.

Selection Notes

Select this component when Schmitt-trigger action is required to clean noisy input signals or convert slow-rising waveforms into sharp digital transitions. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Consider the 14-pin SOIC package for ease of automated assembly if space constraints allow. Verify that the 2 V to 5.5 V supply range aligns with your system's power rails.

Part Context

This component is part of the SN74AHC14 family of hex Schmitt-trigger inverters. The 'D' suffix indicates the 14-pin Small Outline Integrated Circuit (SOIC) package type. The 'RE4' suffix typically denotes tape and reel packaging configuration along with lead-free and environmental compliance attributes. It serves as a functional equivalent to other industry-standard hex inverter ICs requiring hysteresis.

Replacement Considerations

Compatible substitutes include the SN74AHC14DR and SN74AHC14PWG4. These alternatives share identical logical functionality and pinout configurations but may differ in package style or manufacturing revisions. Verify that any replacement maintains the same voltage, current, and temperature specifications.
