Overview
The SN74AHC02QWBQARQ1 is an automotive-grade quadruple 2-input positive-NOR gate from the Texas Instruments SN74AHC02-Q1 series. 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. The device utilizes a WQFN-14 (BQA) package with dimensions of 3 mm by 2.5 mm. Electrical characteristics include high-level output currents up to -8 mA at 5 V and low-level output currents up to 8 mA at 5 V. Switching performance at 5 V features propagation delays ranging from 3.6 ns to 8.5 ns depending on load capacitance.
Feature Summary
- Qualified for automotive applications
- Wide supply voltage operation from 2 V to 5.5 V
- Extended operating temperature range up to 125°C
Applications
- Automotive electronic systems
- Logic signal processing in vehicles
- Boolean NOR function implementation
Procurement Notes
Verify the specific BQA package variant matches the design requirements. Confirm that the Q1 suffix indicates automotive qualification status. Ensure the ordering part number aligns with the desired production status, as some variants may be marked as NRND. Check the latest Package Option Addendum for current availability and material specifications before finalizing procurement.
Selection Notes
Select this component when automotive reliability and extended temperature ranges are required. The AHC logic family provides compatibility with standard CMOS inputs while offering faster switching speeds than legacy HC families. The WQFN package is suitable for space-constrained PCB layouts requiring thermal pad soldering for optimal heat dissipation.
Part Context
This device belongs to the SN74AHC02-Q1 family of quadruple 2-input NOR gates designed specifically for automotive environments. It shares functional similarities with other members of the AHC series but is distinguished by its automotive qualification and specific package options like the WQFN-14 used in this part number.
Replacement Considerations
SN74AHC02QPWRG4Q1 is listed as an active alternative in the same family.
