74LVC1G07QW5-7

Overview

The Diodes Incorporated 74LVC1G07QW5-7 is an automotive-compliant single buffer featuring an open-drain output, designed for operation within a power supply range of 1.65V to 5.5V. It provides a maximum sink current of 32mA at 5V and supports partial power-down applications via IOFF circuitry. The device inputs accept up to 5.5V regardless of VCC level, facilitating mixed-voltage environments. Propagation delay ranges from 0.5ns to 8.4ns depending on voltage. It operates across Grade 1 ambient temperatures from -40°C to +125°C.

Feature Summary

• AEC-Q100 qualified with Grade 1 temperature rating (-40°C to +125°C)
• Open-drain output enables active-low wired-OR or active-high wired-AND functions
• IOFF circuitry prevents damaging backflow during partial power-down states
• Inputs tolerate 5.5V independent of the VCC supply level

Applications

• Voltage level shifting in mixed-voltage systems
• Power down signal isolation
• Automotive applications requiring specific change control
• Industrial computing and automation controls

Procurement Notes

Verify that the ordering suffix W5 corresponds to the SOT25 package configuration required for your PCB layout. Confirm AEC-Q100 qualification and PPAP capability are necessary for your specific automotive application requirements. Ensure the design accommodates the open-drain nature of the output by including appropriate pull-up components if logic high levels are needed.

Selection Notes

Select this component when an open-drain buffer is required for wired-logic implementations or driving loads exceeding standard CMOS capabilities. It is suitable for designs needing robust ESD protection and tolerance to 5.5V inputs while operating at lower supply voltages. Consider the thermal resistance characteristics of the SOT25 package for heat dissipation in dense layouts.

Part Context

This part belongs to the 74LVC1G07Q family of single buffers with open-drain outputs manufactured by Diodes Incorporated. The 'Q' designation indicates AEC-Q100 qualification for automotive use, while 'W5' specifies the SOT25 surface-mount package. It is distinct from non-automotive variants and push-pull output devices like the 74LVC1G07.

Replacement Considerations

The 74LVC1G07SE-7 serves as a package alternative using the SOT353 footprint. Verify pin compatibility and electrical specifications against the target replacement datasheet before implementation.

FAQ

How does the IOFF feature function?

The IOFF circuitry disables the output to prevent damaging current backflow when the device is powered down.

What is the input voltage tolerance?

The inputs accept up to 5.5V regardless of the VCC level, allowing use in mixed-voltage environments.
