SN74AHCT14QDRG4Q1

Overview

The SN74AHCT14QDRG4Q1 is an automotive-grade hex Schmitt-trigger inverter manufactured by Texas Instruments. It belongs to the SN74AHC-Q1 series, utilizing advanced CMOS technology for high-speed operation. The device features six independent inverters with Schmitt-trigger inputs to ensure clean signal transitions. It operates within a supply voltage range of 2 V to 5.5 V and supports a wide operating temperature range from -40°C to +125°C. Packaged in a 14-pin SOIC (D) format, it meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Automotive grade qualification compliant with AEC-Q100 standards
• Hex Schmitt-trigger configuration for noise immunity
• Wide supply voltage compatibility from 2 V to 5.5 V
• Extended industrial temperature range up to 125°C

Applications

• Automotive electronic control units
• Signal conditioning in noisy environments
• Pulse width modulation circuits
• Oscillator timing networks

Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the Q1 designation aligns with required automotive reliability standards for your specific application tier. Ensure the SOIC-14 package dimensions match your PCB footprint requirements. Cross-reference the datasheet revision date to confirm current electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when Schmitt-trigger hysteresis is required to mitigate signal noise on input lines. The AHCT series ensures TTL-compatible logic levels while maintaining CMOS low power consumption. Consider the 14-SOIC package for surface-mount assembly constraints. Verify that the 2V to 5.5V operating range covers all intended supply rail variations in the target system design.

Part Context

This part is part of the SN74AHC-Q1 family of automotive logic devices. It shares functional similarities with other hex inverters but distinguishes itself through integrated Schmitt-trigger inputs. The Q1 suffix denotes automotive qualification, differentiating it from standard commercial variants like the SN74AHCT14. The G4 suffix typically relates to packaging and environmental compliance attributes defined by Texas Instruments.

Replacement Considerations

Direct substitutes include other AEC-Q100 qualified hex Schmitt-trigger inverters from Texas Instruments such as the SN74AHC14QDRQ1. Ensure any replacement maintains the same SOIC-14 package and voltage range. Verify pinout compatibility if substituting with non-TI manufacturers' equivalents.
