74LVC1G07SE-7

Overview

The 74LVC1G07SE-7 is a single buffer gate with an open-drain output manufactured by Diodes Incorporated. It operates within a power supply range of 1.65V to 5.5V and features inputs tolerant to 5.5V for mixed-voltage environments. The device supports partial power-down applications via IOFF circuitry, which disables the output to prevent damaging current backflow. It provides a maximum sink current of 32mA and includes ESD protection exceeding 2000-V Human Body Model and 1000-V Charged Device Model standards.

Feature Summary

• Open-drain output configuration enabling active-low wired-OR or active-high wired-AND functions when connected to other open-drain outputs.
• IOFF circuitry designed to disable the output during partial power-down modes, preventing damaging current backflow.
• Input tolerance up to 5.5V allows direct interface with TTL levels and operation in mixed voltage environments.

Applications

• Voltage level shifting
• Power down signal isolation
• General purpose logic

Procurement Notes

Verify that the specific part number suffix matches the required package type, as the 74LVC1G07 series is available in multiple packages including SOT25, SOT353, SOT553, and various DFN options. Confirm compliance requirements such as RoHS and Halogen-free status directly with the manufacturer documentation. Ensure the selected variant meets the specific thermal resistance and moisture sensitivity level requirements for the intended application environment.

Selection Notes

Select this component when an open-drain buffer is required for driving loads that necessitate wired-logic configurations or interfacing with higher voltage domains than the logic supply. The wide operating voltage range from 1.65V to 5.5V makes it suitable for diverse digital systems. Consider the IOFF feature if the design requires safe disconnection during power-down states to protect downstream components from back-powering.

Part Context

This component belongs to the 74LVC1G07 series of single-buffer drivers produced by Diodes Incorporated. The 'SE' designation specifically identifies the SOT353 surface-mount package variant. The series is part of the broader LVC logic family, characterized by low voltage CMOS technology designed for high-speed operation with low power consumption across a wide supply voltage range.

Replacement Considerations

Direct substitutes include the SN74LVC1G07DCKR from Texas Instruments and the NL17SZ07DFT2G from onsemi. These alternatives offer similar logical functionality and pinout compatibility but may differ in specific electrical characteristics, package dimensions, or manufacturing processes. Verify all parameters against the original datasheet before implementation.
