SN74LVC11AWBQARQ1

Inverter Gates Overview

The SN74LVC11AWBQARQ1 is an automotive-grade triple 3-input AND gate from Texas Instruments, qualified to AEC-Q100 standards. It operates within a supply voltage range of 1.1V to 3.6V and features 5.5V tolerant inputs. The device utilizes a 14-pin WQFN (WBQA) package with wettable flanks for enhanced inspection reliability. Electrical specifications include a propagation delay of up to 23ns at 1.2V and latch-up performance exceeding 250mA per JESD 17.

Inverter Gates Feature Summary

• AEC-Q100 qualification for automotive applications across temperature grades
• Wettable flank QFN package design facilitating automatic optical inspection
• 5.5V tolerant input pins allowing compatibility with higher voltage logic levels
• Balanced CMOS push-pull outputs providing symmetric current sourcing and sinking capabilities

Inverter Gates Applications

• Combining power good signals for system monitoring
• Enabling digital signals in control circuits
• Directly controlling motor controller reset pins via combined logic inputs

Inverter Gates Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the wettable flank variant is selected if automated optical inspection compliance is mandatory for the assembly process. Ensure the component meets the specific AEC-Q100 grade requirements for the target automotive application environment.

Inverter Gates Selection Notes

Select this component when three independent logic inputs must be combined into a single active-high output within automotive systems. The 5.5V input tolerance allows interfacing with 5V logic domains while operating on lower supply voltages. The WQFN package is suitable for space-constrained designs requiring reliable solder joint verification through wettable flank technology.
