SN74AHC14PWRG3-J

Overview

The SN74AHC14PWRG3-J is an enhanced product hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features a TSSOP-14 package with 14 pins. The device supports an operating temperature range from -55°C to 125°C. Key electrical characteristics include a maximum low-level output current of 0.05 A and a load capacitance specification of 50 pF. This component is designed for high-speed CMOS logic applications requiring superior noise immunity.

Feature Summary

• Hex Schmitt-trigger inverters providing superior noise immunity
• Enhanced product variant with extended temperature capability down to -55°C
• High-speed CMOS technology compatible with standard logic interfaces

Applications

• Signal conditioning for noisy environments
• Waveform shaping and pulse generation
• Digital interface circuits requiring hysteresis

Procurement Notes

Verify the specific 'J' suffix designation, which indicates an enhanced product variant, against standard SN74AHC14PWRG3 specifications. Confirm that the extended temperature range (-55°C) aligns with your system requirements. Ensure the TSSOP-14 package dimensions match your PCB footprint design. Cross-reference the RoHS compliance status with current regulatory standards for your target market.

Selection Notes

Select this component when application demands exceed standard commercial grade temperature ranges, specifically requiring operation down to -55°C. The Schmitt-trigger input is essential for signals with slow rise times or significant noise. Compare the 0.05 A output drive capability against load requirements. Consider the TSSOP-14 package for space-constrained surface-mount designs where thermal performance at extreme temperatures is critical.

Part Context

This part belongs to the Texas Instruments SN74AHC14 family of hex Schmitt-trigger inverters. The 'J' suffix typically denotes an enhanced product version, often featuring wider operating temperature ranges compared to standard commercial variants. It utilizes advanced CMOS technology to achieve high speed while maintaining low power consumption, fitting within the broader AHC/VHC logic series ecosystem.

Replacement Considerations

Direct substitutes include SN74AHC14PWRG3, though verification of the -55°C lower temperature limit is required as standard versions may only support -40°C. Other family members like SN74AHC14PW offer similar functionality but may lack the specific enhanced product designation.
