SN74AHC14QPWRQ1

Overview

The SN74AHC14QPWRQ1 is an automotive-grade, six-channel inverter from Texas Instruments' AHC logic family. It operates within a supply voltage range of 2 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device provides balanced push-pull outputs with a maximum drive current of 8 mA at both high and low states. It is qualified under AEC-Q100 standards and supports an operating temperature range from -40°C to +125°C. Packaged in a 14-pin TSSOP, it offers very high-speed performance with propagation delays typically between 5 ns and 10 ns.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle electronics.
• Schmitt-trigger input configuration ensures clean signal transitions and noise filtering.
• Wide supply voltage operation supports diverse power domains from 2 V to 5.5 V.
• Balanced push-pull output structure provides symmetric drive capability.

Applications

• Signal conditioning and waveform shaping in automotive control modules
• Clock buffer and driver applications requiring noise immunity
• Level shifting between different voltage domains in vehicle networks

Procurement Notes

Verify the complete part number against official Texas Instruments documentation to ensure correct package type and automotive grade designation. Confirm that the specific suffix matches the required tape-and-reel quantity and packaging format. Cross-reference the manufacturer date code and lot traceability requirements with your quality management system specifications before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring robust noise rejection via Schmitt triggers and compliance with automotive reliability standards. Ensure the 2 V to 5.5 V supply range aligns with the target circuit's power architecture. Verify that the TSSOP-14 package dimensions fit the available PCB footprint and thermal constraints of the assembly process.

Part Context

This device belongs to the SN74AHC14Q series, representing Texas Instruments' automotive-qualified AHC logic line. It shares functional similarities with other inverters in the family but is distinguished by its specific automotive rating and Schmitt-trigger input characteristics. The Q1 suffix denotes its qualification for use in demanding automotive environments.

Replacement Considerations

Direct substitutes include other AEC-Q100 qualified six-channel Schmitt trigger inverters from the same manufacturer family, such as the SN74AHC14QDRQ1 or SN74AHC14QDBVRQ1, provided the pinout and electrical parameters remain compatible.
