74LVC07AD/AUJ

Overview

The 74LVC07AD/AUJ is a hex buffer with open-drain outputs manufactured by Nexperia. It operates within a supply voltage range of 1.2 V to 5.5 V and features Schmitt-trigger inputs for tolerance against slow signal transitions. The device provides direct interface capability with TTL levels and includes overvoltage tolerant inputs up to 5.5 V. It complies with JEDEC standards for various voltage domains, including JESD8-7A, JESD8-5A, and JESD8-C/JESD36. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Operating temperatures are specified from -40 °C to +85 °C and -40 °C to +125 °C.

Feature Summary

• Hex buffer configuration with open-drain outputs suitable for interfacing with 5 V logic systems.
• Schmitt-trigger action at all inputs ensures tolerance for slower input rise and fall times.
• CMOS technology delivers low power consumption while maintaining direct interface compatibility with TTL levels.

Applications

• Translating signals between mixed 3.3 V and 5 V environments.
• Interfacing 3.3 V or 5 V devices with 5 V tolerant logic circuits.
• General purpose buffering in digital logic applications requiring open-drain output characteristics.

Procurement Notes

Verify the specific package variant required, as the 74LVC07AD designation corresponds to the SO14 plastic small outline package (SOT108-1). Confirm that the application environment falls within the specified temperature ranges of -40 °C to +85 °C or -40 °C to +125 °C. Ensure supply voltage constraints remain within the 1.2 V to 5.5 V operational limits defined in the recommended operating conditions.

Selection Notes

Select this component when an open-drain output topology is necessary for wired-AND configurations or level shifting. The wide supply voltage range supports operation across multiple logic families. Verify that the required package type matches the design footprint, specifically the SO14 form factor for the AD suffix. Consider the thermal dissipation requirements if operating near the upper temperature limits.

Part Context

This part belongs to the 74LVC07A family of hex buffers produced by Nexperia. The 'AD' suffix identifies the specific SO14 package variant. The series utilizes CMOS technology optimized for low-voltage operation while maintaining compatibility with higher voltage interfaces. This family is designed for general-purpose digital buffering tasks in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include the SN74LVC07AD from Texas Instruments. Other compatible alternatives may include parts from Diodes Incorporated or onsemi, provided they match the open-drain output requirement and pinout configuration.

FAQ

What is the function of the open-drain outputs?

The open-drain outputs allow the device to interface directly with 5 V logic systems and support wired-AND connections, enabling use as translators in mixed voltage environments.

How does the device handle slow input signals?

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times, ensuring stable switching behavior.
