SN74ACT14NS

Overview

The SN74ACT14NS is a hex inverter integrated circuit from the Texas Instruments SN74ACT series. It features TTL-compatible Schmitt-trigger inputs designed to support slow and noisy input signals. The device operates within a supply voltage range of 4.5 V to 5.5 V and provides continuous output drive currents of ±24 mA at 5 V. It utilizes a 14-pin PDIP package for through-hole mounting.

Feature Summary

• Hex inverter configuration with six independent channels
• TTL-compatible Schmitt-trigger inputs for noise immunity
• Continuous ±24 mA output drive capability at 5 V

Applications

• Inverting digital signals
• Debouncing switches
• Synchronizing inverted clock inputs

Procurement Notes

Verify the specific suffix 'N' corresponds to the PDIP-14 through-hole package variant when sourcing. Confirm that the component meets RoHS requirements as indicated by manufacturer specifications. Ensure compatibility with standard 5 V logic systems given the specified operating voltage range.

Selection Notes

Select this component when slow or noisy signal transitions require hysteresis provided by Schmitt triggers. It serves as a direct replacement for older 74LS14 devices where higher speed and CMOS compatibility are needed. Verify that the through-hole packaging aligns with the target PCB design constraints.

Part Context

This part belongs to the SN74ACT family, which combines the high-speed performance of AC logic with CMOS power consumption characteristics. The inclusion of Schmitt triggers distinguishes it from standard inverters like the SN74ACT04, making it suitable for waveform shaping applications.
