SN74AHCT14RGYR

Overview

The SN74AHCT14RGYR is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes CMOS logic technology. The component features six independent circuits housed in a 14-VQFN package with an exposed pad. It supports surface-mount installation and functions across a temperature range of -40°C to +125°C. Key electrical characteristics include Schmitt-trigger inputs for noise immunity and standard CMOS output levels.

Feature Summary

• Integrates six independent inverting channels with Schmitt-trigger input thresholds
• Operates at a fixed 5 V supply voltage range compatible with standard TTL logic families
• Provides enhanced noise filtering and signal conditioning through hysteresis
• Utilizes low-power CMOS technology for efficient performance

Applications

• Signal conditioning for noisy digital environments
• Waveform shaping from slow or distorted input signals
• Threshold detection circuits requiring defined switching points
• Oscillator circuits utilizing RC timing networks

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm the package variant corresponds to the 14-VQFN footprint with an exposed thermal pad. Ensure the voltage grade aligns with the 4.5 V to 5.5 V operational requirement. Check moisture sensitivity level handling procedures prior to assembly.

Selection Notes

Select this component when precise switching thresholds are necessary to prevent multiple transitions due to signal noise. It is suitable for applications interfacing between different logic families where voltage translation is not required but noise immunity is critical. Consider the thermal performance of the VQFN package for high-density designs.

Part Context

This device belongs to the SN74AHC and SN74AHCT logic families, which offer high-speed operation and wide operating voltage ranges. The 'T' designation indicates compatibility with 5 V TTL input levels, distinguishing it from the AHC series which uses CMOS input thresholds. It serves as a specialized inverter variant within the broader hex inverter category.

Replacement Considerations

Direct functional substitutes include the SN74AHC14RGYR, though input threshold levels differ. Other compatible options may include equivalent hex Schmitt-trigger inverters from other manufacturers that match the 14-VQFN package and 5 V supply requirements.
