Overview
The SN74AC08WBQARQ1 is an automotive-grade, quad dual-input positive-AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40°C to +125°C. The device complies with AEC-Q100 standards for Grade 1. It features a maximum propagation delay of 7.5 ns at 5 V and accepts input voltages up to 6 V. Packaged in a WQFN-14 format, it is designed for robust digital logic applications.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
- Wide power supply operation supporting 2 V to 6 V for flexible system integration.
- High-speed performance with a maximum propagation delay of 7.5 ns at 5 V.
- Input tolerance allows acceptance of voltages up to 6 V regardless of VCC level.
Applications
- Digital logic circuits requiring reliable AND operations.
- LED driving interfaces in automotive systems.
- Digital signal processing tasks.
- Control and automation systems.
Procurement Notes
Verify the specific suffix WBQARQ1 against the official Texas Instruments datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 Grade 1 requirements for your target automotive application. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity before procurement.
Selection Notes
Select this component when designing automotive electronics that require high-speed AND gating within a 2 V to 6 V supply range. It is suitable for systems needing inputs tolerant to 6 V signals while operating at lower voltages. Consider the WQFN-14 package for space-constrained PCB layouts. Verify thermal management capabilities for the -40°C to +125°C operating range.
Part Context
This part belongs to the SN74AC08-Q1 family of automotive quad dual-input positive-AND gates. It shares functional compatibility with standard SN74AC08 devices but includes enhanced durability and qualification for automotive use. The series is designed to replace legacy logic families in modern automotive digital control architectures.
Replacement Considerations
Direct replacements include other SN74AC08-Q1 variants with compatible suffixes. Non-automotive SN74AC08 devices may function electrically but lack the required AEC-Q100 certification. Verify pinout and electrical characteristics match before substituting.
