SN74ACT14WBQARQ1

Overview

The SN74ACT14WBQARQ1 is an automotive-grade hex inverter featuring TTL-compatible Schmitt-trigger inputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports continuous output drive currents of ±24 mA at 5 V, with short-term capability up to ±75 mA. The device ensures signal integrity through noise filtering and includes a maximum propagation delay of 9.5 ns. Packaged in a WQFN-14 housing with wettable flanks, it meets AEC-Q100 Grade 1 standards for operation between -40°C and +125°C.

Feature Summary

• TTL-compatible Schmitt trigger inputs filter slow or noisy signals
• High-output drive capability supports 50Ω transmission lines
• AEC-Q100 qualified for automotive reliability requirements

Applications

• Digital signal inversion
• Switch debouncing
• Synchronous inverted clock input conditioning

Procurement Notes

Verify the specific WBQARQ1 suffix against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compliance with export regulations if shipping from restricted regions. Confirm that the component matches the required AEC-Q100 Grade 1 temperature rating for your target application environment before finalizing procurement.

Selection Notes

Select this component when designing automotive circuits requiring robust noise immunity on digital lines. The Schmitt trigger action makes it suitable for interfaces with slow-rising signals. Verify that the 4.5 V to 5.5 V operating range aligns with the system power supply. The WQFN-14 package is appropriate for applications prioritizing compact board space and thermal performance.

Part Context

This part belongs to the SN74ACT14-Q1 family of hex inverters designed specifically for automotive electronics. It shares functional characteristics with standard industrial logic but adheres to stricter automotive qualification standards. The device serves as a fundamental building block for signal conditioning and timing correction in vehicle control modules.

Replacement Considerations

Direct substitutes include other AEC-Q100 qualified hex inverters with Schmitt triggers, such as the SN74ACT14DWR or SN74ACT14DR. Cross-reference pinouts and electrical parameters carefully to ensure compatibility with existing PCB layouts and signal requirements.
