SN74AHC14N

Overview

The SN74AHC14N 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 CMOS logic technology. The device contains six independent inverters with Schmitt-trigger inputs, packaged in a 14-pin PDIP format. It supports through-hole mounting and functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Hex configuration providing six independent inverting channels
• Schmitt-trigger input architecture for noise immunity
• CMOS logic construction for low power consumption
• Wide supply voltage compatibility

Applications

• Signal conditioning for noisy environments
• Waveform shaping and conversion
• Pulse generation circuits
• Oscillator timing networks

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm package type and temperature grade. Ensure the component matches the required logic family specifications for your design. Confirm RoHS compliance status if environmental regulations apply to your project requirements.

Selection Notes

Select this component when multiple inverting stages with hysteresis are required in a single package. The wide voltage range allows flexibility in system design. Consider the PDIP package constraints for PCB layout and thermal management compared to surface-mount alternatives.

Part Context

This part belongs to the SN74AHC14 series of hex Schmitt-trigger inverters. It is designed for high-speed digital applications requiring clean signal transitions. The AHC series offers performance comparable to older technologies while maintaining lower power dissipation typical of modern CMOS devices.

Replacement Considerations

Check for direct pin-compatible substitutes such as the SN74AHCT14N for TTL-compatible input levels or other AHC-series variants. Verify that any replacement maintains the same Schmitt-trigger characteristics and voltage operating ranges.
