74AHCT1G07QSE-7

Overview

The 74AHCT1G07QSE-7 is a single non-inverting buffer with open-drain output from the AHCT logic family, designed for 4.5V to 5.5V operation. It features Schmitt trigger inputs and automotive-grade reliability (AEC-Q100). The device operates within an ambient temperature range of -40°C to +125°C. Electrical characteristics include an 8mA low-level output sink current at VCC = 4.5V and balanced propagation delays. Typical propagation delay is 2.8ns at VCC = 5V with 15pF load. Input capacitance is typically 1.5pF.

Feature Summary

• Open-drain output configuration allows wired-OR or wired-AND implementation when connected to other open-drain outputs.
• Schmitt trigger action on all inputs provides tolerance for slower input rise and fall times.
• Inputs are not limited by VCC, allowing flexible interfacing capabilities.
• Automotive Grade 1 qualification ensures suitability for high-reliability applications.

Applications

• Automotive applications requiring specific change control
• Industrial computing, controls, and automation systems
• High reliability networking and communications equipment

Procurement Notes

Verify that the ordering suffix 'SE' corresponds to the SOT353 package as specified in the datasheet. Confirm AEC-Q100 qualification status if automotive compliance is required. Ensure supply voltage remains within the 4.5V to 5.5V range during operation. Check RoHS3 and halogen-free compliance requirements against project specifications.

Selection Notes

Select this component when a single-channel non-inverting buffer with open-drain capability is needed. The AHCT series ensures compatibility with standard CMOS logic levels at 5V. Consider the SOT353 package size constraints and thermal resistance values for PCB layout planning. Verify that the open-drain nature meets the system's pull-up resistor requirements.

Part Context

This part belongs to Diodes Incorporated's 74AHCT1GxxQ automotive logic series. It shares the same logical function as other variants but differs in packaging options such as SOT25. The Q suffix indicates AEC-Q100 qualification, while the SE suffix specifically denotes the SOT353 surface-mount package.

Replacement Considerations

The 74AHCT1G07QW5-7 serves as a direct functional substitute using the SOT25 package instead of SOT353. Both parts share identical electrical characteristics and automotive qualifications. Verify pinout compatibility and physical footprint differences before substitution.
