Overview
The SN74AC11IDRQ1 is an automotive-grade triple 3-input positive-AND gate manufactured by Texas Instruments. It belongs to the SN74AC11-Q1 series, designed for high-speed digital logic applications. The device 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. Key electrical characteristics include a propagation delay of 7.5 ns at 5 V with 50 pF load, and symmetrical output drive currents of ±24 mA. It is housed in a 14-TSSOP package.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for high reliability in vehicle electronics.
- Wide supply voltage operation ranging from 2 V to 6 V for flexible system integration.
- High-speed performance with low propagation delay suitable for demanding digital interfaces.
- Strong output drive capability providing ±24 mA current for robust signal transmission.
Applications
- Automotive infotainment and display control systems
- Body control modules requiring reliable logic gating
- Industrial automation logic circuits
- Communication equipment interface protection
Procurement Notes
Verify that the specific part number suffix matches the required automotive grade and package type. Confirm AEC-Q100 certification status if mandated by your design specifications. Ensure the ordering information aligns with the intended volume and tape-and-reel requirements. Cross-reference the manufacturer's latest datasheet for any potential pinout or electrical parameter updates before finalizing procurement.
Selection Notes
Select this component when automotive reliability and wide voltage tolerance are critical. The AC series offers faster switching speeds compared to standard 74LS counterparts while maintaining CMOS power efficiency. Consider the TSSOP package constraints for PCB layout. Verify that the input voltage levels are compatible with the driving source across the entire operating temperature range to ensure correct logic state interpretation.
Part Context
This component is part of the SN74AC11-Q1 family of triple 3-input AND gates. It shares functional similarities with non-automotive variants like the SN74AC11 but includes enhanced testing for automotive environments. The 'I' suffix typically denotes the TSSOP-14 package, while 'DRQ1' indicates reel packaging and automotive qualification. It serves as a specialized digital logic solution for harsh operating conditions.
Replacement Considerations
SN74AC11DRQ1: Same function and automotive grade but in SOIC-14 package; requires footprint adaptation. SN74ACT11DRQ1: Faster speed but limited to 5V supply; incompatible with lower voltage systems. SN74AC11DWRQ1: Alternative TSSOP variant; verify pin compatibility and thermal characteristics.
