74LVC1G07QSE-7

Overview

The 74LVC1G07QSE-7 is an automotive-compliant single buffer with open-drain output from Diodes Incorporated. 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 supports partial power-down via IOFF circuitry, preventing backflow current. It provides a maximum sink current of 32mA at 5V and 24mA at 3.3V. Operating temperature spans -40°C to +125°C (Grade 1). Propagation delay ranges from 0.5ns to 8.4ns depending on voltage. It is housed in a SOT353 package.

Feature Summary

• Open-drain output enables active-low wired-OR or active-high wired-AND logic functions
• IOFF circuitry disables the output during partial power-down to prevent damaging current backflow
• Inputs accept up to 5.5V regardless of VCC level, facilitating mixed-voltage system integration
• AEC-Q100 qualified with Grade 1 ambient temperature operation (-40°C to +125°C)

Applications

• Voltage level shifting between different logic families
• Power down signal isolation in mixed-voltage systems
• Automotive applications requiring specific change control and AEC-Q100 qualification

Procurement Notes

Verify that the ordering suffix 'SE' corresponds specifically to the SOT353 package variant as documented in the manufacturer's datasheet. Confirm that the 'Q' designation indicates AEC-Q100 automotive qualification and PPAP capability. Ensure the '-7' suffix matches the required tape and reel packing quantity. Cross-reference the full part number against official Diodes Incorporated documentation to validate all functional and packaging specifications before procurement.

Selection Notes

Select this component when an open-drain buffer is required for wired-logic implementations or driving loads exceeding standard push-pull capabilities. The wide input voltage tolerance allows interfacing with 5.5V signals even at lower supply voltages. The AEC-Q100 qualification makes it suitable for automotive environments. Consider the propagation delay characteristics relative to the target operating voltage to ensure timing requirements are met within the specified temperature range.

Part Context

This device belongs to the 74LVC1G07 series of single buffers with open-drain outputs manufactured by Diodes Incorporated. The 'LVC' designation indicates the low-voltage CMOS logic family designed for 1.65V to 5.5V operation. The '1G' prefix signifies a single gate configuration. The 'Q' suffix denotes automotive-grade qualification compliant with AEC-Q100 standards, ensuring reliability for Grade 1 temperature operations in demanding environments.

Replacement Considerations

The 74LVC1G07W5-7 serves as a direct alternative utilizing the SOT25 package instead of SOT353. Both variants share identical electrical characteristics, pinouts, and functionality. Verify that the PCB footprint accommodates the specific package dimensions of the substitute. Ensure the replacement maintains the required AEC-Q100 qualification if automotive compliance is mandatory for the application.
