SN74HCS11QDRQ1

Inverter Gates Overview

The SN74HCS11QDRQ1 is an automotive-grade CMOS logic gate manufactured by Texas Instruments. It contains three independent 3-input AND gates housed in a 14-pin SOIC (DW) package. 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 5 ns, low-level output current of 7.8 mA, and high-level output current of -7.8 mA. It is qualified under AEC-Q100 standards for automotive applications.

Inverter Gates Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Schmitt-trigger inputs provide noise filtering and improved switching performance.
• Wide supply voltage operation ranging from 2 V to 6 V for flexible power integration.

Inverter Gates Applications

• Automotive electronic control units requiring robust logic gating.
• High-speed data processing circuits in automotive infotainment systems.
• Signal conditioning interfaces in harsh electromagnetic environments.

Inverter Gates Procurement Notes

Verify the specific suffix 'QDRQ1' to ensure the correct SOIC-14 package and tape-and-reel packaging configuration. Confirm that the component meets the required AEC-Q100 grade specifications for your target automotive application. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and revision history before procurement.

Inverter Gates Selection Notes

Select this component when designing automotive systems that require Schmitt-trigger inputs for noise immunity alongside standard AND logic functionality. The HCS series offers faster propagation delays compared to standard HC devices while maintaining CMOS compatibility. Ensure the design accommodates the 2 V to 6 V supply range and the thermal requirements of the -40°C to +125°C operating window.

Inverter Gates Part Context

This part belongs to the SN74HCSx1 family of automotive-grade logic ICs from Texas Instruments. The HCS series combines the speed of AC/ACT logic with the low power consumption of HC/HCT logic. The 'Q' suffix indicates automotive qualification, while 'RQ1' specifies the reel packaging and RoHS compliance. It serves as a specialized variant for demanding automotive electronics.

Inverter Gates Replacement Considerations

Direct pin-to-pin replacements may include other SN74HCS11 variants with different packaging or non-automotive grades. Verify that any substitute maintains the same Schmitt-trigger input characteristics and AEC-Q100 qualification if automotive reliability is mandatory. Check datasheet differences for propagation delay and output drive strength variations.
