SN74AHC04QWBQARQ1

Overview

The SN74AHC04QWBQARQ1 is an automotive-grade hex inverter utilizing Enhanced-Performance Implanted CMOS (EPIC) technology. It operates within a supply voltage range of 2 V to 5.5 V and supports a wide operating temperature from -40°C to +125°C. The device contains six independent inverters performing the Boolean function Y = A. It features low static power consumption with a maximum ICC of 20 µA at 5.5 V. Propagation delays are specified as 8.5 ns maximum at 5 V with 50 pF load, and 13 ns maximum at 3.3 V with 50 pF load. The component is housed in a WQFN-14 package.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for robust performance in vehicle environments
• Six independent inverter channels providing high-density logic inversion capabilities
• Wide supply voltage operation supporting diverse system power architectures
• Low power dissipation characteristics suitable for energy-efficient designs

Applications

• Synchronizing inverted clock inputs

Procurement Notes

Verify the specific ordering suffix matches the required package type and reel configuration. Confirm RoHS compliance status and moisture sensitivity level ratings prior to assembly. Ensure thermal pad soldering requirements are met for optimal heat dissipation in the WQFN package. Check for any recent product change notifications affecting pinout or electrical specifications.

Selection Notes

Select this component when automotive reliability and wide voltage tolerance are required. The EPIC process offers improved noise immunity compared to standard CMOS technologies. Consider the propagation delay specifications relative to the target clock frequencies. Evaluate the thermal resistance values against the expected ambient conditions and board layout constraints.

Part Context

This part belongs to the SN74AHC04-Q1 family of hex inverters designed specifically for automotive applications. It shares functional compatibility with other members of the AHC series but includes enhanced durability features. The BQA suffix indicates the WQFN package variant, distinguishing it from SOIC or TSSOP versions within the same logical family.
