SN74AHC14PWRE4

Overview

The SN74AHC14PWRE4 is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features six independent inverting channels. The device utilizes a 14-pin TSSOP surface-mount package. Key electrical specifications include a maximum propagation delay of 10.6 ns at 5 V with a 50 pF load, low static current consumption of 1 µA, and output drive capabilities of 8 mA for both high and low states. It supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates six independent Schmitt-trigger inverters for noise filtering and signal conditioning
• Operates across a wide supply voltage range from 2 V to 5.5 V
• Provides robust output drive capability of 8 mA for high and low logic states
• Designed for extended industrial temperature operation up to +125°C

Applications

• Signal conditioning for noisy digital environments
• Waveform shaping and pulse generation
• Oscillator circuits requiring hysteresis
• Level shifting between different voltage domains

Procurement Notes

Verify the specific ordering suffix 'E4' confirms lead-free composition and RoHS compliance as per manufacturer standards. Confirm the package type matches the required 14-TSSOP footprint for PCB layout compatibility. Ensure the component status is reviewed, as availability may vary based on production lifecycle updates. Cross-reference the datasheet revision date to ensure alignment with current design specifications and electrical characteristics.

Selection Notes

Select this component when application requirements demand hysteresis to prevent false triggering from slow-rising signals or electrical noise. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS compatibility. Verify that the 2 V to 5.5 V supply range aligns with the system power architecture. Consider the 14-TSSOP package dimensions against available board space constraints.

Part Context

This part belongs to the SNx4AHC14 family of hex Schmitt-trigger inverters. It shares functional similarities with other Texas Instruments logic devices but is distinct due to its integrated hysteresis characteristics. The 'E4' suffix typically denotes environmental compliance attributes such as lead-free manufacturing. It serves as a specialized variant within the broader AHC logic portfolio designed for high-speed, low-power applications.

Replacement Considerations

SN74AHC14PWR is a direct pin-compatible alternative within the same product family.
