74LVC1G126QSE-7

Overview

The 74LVC1G126QSE-7 is an automotive-compliant, single-channel non-inverting buffer with a 3-state output. It operates within a supply voltage range of 1.65V to 5.5V and features inputs tolerant to 5.5V for mixed-voltage environments. The device includes IOFF circuitry to support partial power-down applications by disabling outputs and preventing backflow current. It is qualified under AEC-Q100 Grade 1 standards, ensuring reliability in high-temperature conditions ranging from -40°C to +125°C.

Feature Summary

• AEC-Q100 Grade 1 qualification for automotive applications
• IOFF circuitry supports partial power-down mode operation
• Inputs accept up to 5.5V for mixed-voltage compatibility

Applications

• Voltage level shifting
• Power down signal isolation
• Industrial computing and controls
• High reliability networking and communications

Procurement Notes

Verify the component matches Diodes Incorporated part number 74LVC1G126QSE-7. Confirm the package type is SOT353 and the suffix indicates a 7-inch tape and reel quantity of 3000 units. Ensure the device meets AEC-Q100 Grade 1 requirements and RoHS compliance specifications before integration into designs.

Selection Notes

Select this component when designing systems requiring a single-channel buffer with 3-state control and automotive-grade reliability. It is suitable for mixed-voltage interfaces due to its 5.5V input tolerance. Verify that the operating temperature range of -40°C to +125°C aligns with the environmental constraints of the target application.

Part Context

This component belongs to the 74LVC logic family, designed for low-voltage CMOS applications. It functions as a bus driver providing non-inverting buffering. The 'Q' designation signifies AEC-Q100 qualification, while 'SE' identifies the specific SOT353 surface-mount package configuration used in compact electronic assemblies.

Replacement Considerations

Substitutes must maintain AEC-Q100 Grade 1 qualification and identical pinout configurations. Verify that alternative components support the same 1.65V to 5.5V supply range and possess compatible 3-state output characteristics to ensure functional equivalence in existing circuits.
