SN74LVC11ABQAR

Inverter Gates Overview

The SN74LVC11ABQAR is an automotive-grade triple 3-input AND gate from Texas Instruments, housed in a 14-pin WQFN package. It operates within a supply voltage range of 1.1V to 3.6V and features 5.5V tolerant inputs. The device provides balanced CMOS push-pull outputs with high-level output currents up to -24mA and low-level output currents up to 24mA at 3V. Propagation delay is typically 4.8ns at 2.7V with 50pF load. It supports operating temperatures from -40°C to +125°C and includes ESD protection exceeding 2000V HBM.

Inverter Gates Procurement Notes

Verify the specific suffix 'BQAR' corresponds to the WQFN-14 package and reel packaging configuration required for your assembly process. Confirm that the automotive qualification status aligns with your system's reliability requirements. Ensure input transition rates meet the specified limits to prevent excessive current consumption or oscillations during operation.

Inverter Gates Selection Notes

Select this component when a compact solution for combining three distinct logic signals into a single active-high output is required. The wide supply voltage range allows flexibility in low-power designs. The 5.5V input tolerance simplifies interfacing with 5V systems while the core logic operates at lower voltages. Consider the thermal performance of the WQFN package if multiple devices are densely packed on the PCB.

Inverter Gates Part Context

This part belongs to the SN74LVC11A family of triple 3-input AND gates. The 'BQ' designation indicates automotive grade qualification, while 'AR' specifies the WQFN-14 package type with a tape-and-reel shipping method. It shares functional characteristics with other LVC series logic but is optimized for automotive environmental conditions and specific packaging constraints.

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must not be left floating. They should be terminated to either VCC or ground using pull-up or pull-down resistors, typically around 10kΩ, to prevent undefined operational states and excessive current consumption.

What is the maximum recommended capacitive load?

The device can drive a load with total capacitance less than or equal to 50pF while meeting all data sheet specifications. Exceeding this value may require adding a series resistor to limit output current.
