74LVCE1G07SE-7

Overview

The 74LVCE1G07SE-7 is a single buffer/driver with an open drain output manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.4V to 5.5V and features inputs tolerant up to 5.5V for mixed-voltage environments. The device supports partial power-down applications via I_OFF circuitry, which disables the output to prevent damaging current backflow. It provides a maximum sink current of 32mA and includes ESD protection exceeding 200V (Machine Model) and 2000V (Human Body Model). The component is housed in a SOT-353 package.

Feature Summary

• Open-drain output configuration enabling active-low wired-OR or active-high wired-AND functions when connected to other open-drain outputs.
• Integrated I_OFF circuitry that disables the output during partial power-down mode to prevent 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 the specific ordering suffix SE corresponds to the SOT-353 package type as documented in the manufacturer's ordering information table. Confirm compliance requirements such as RoHS status and lead-free finish directly from the datasheet specifications. Ensure the application environment remains within the recommended operating temperature range of -40°C to +85°C to maintain specified electrical characteristics.

Selection Notes

Select this component when an open-drain output is required for wired-logic implementations or interfacing between different voltage domains. The wide supply voltage range accommodates various system architectures. Verify that the maximum sink current requirement does not exceed the rated capacity. Consider the I_OFF feature if the design requires safe operation during partial power-down states without external control mechanisms.

Part Context

This part belongs to the 74LVCE1Gxx series of low-voltage CMOS logic devices produced by Diodes Incorporated. The series utilizes advanced CMOS technology to achieve low power consumption while maintaining high-speed performance. The LVCE designation indicates specific electrical characteristics tailored for low-voltage applications, distinguishing it from standard LVC or AHCT families.

Replacement Considerations

Direct substitutes include other 74LVCE1G07 variants from Diodes Incorporated with different package codes, such as 74LVCE1G07W5-7 (SOT25) or 74LVCE1G07FZ4-7 (DFN1410), provided the PCB footprint can be adapted. Cross-manufacturer equivalents must be verified against the absolute maximum ratings and electrical characteristics to ensure functional compatibility.

FAQ

How does the I_OFF feature function?

The I_OFF circuitry disables the output when the device is powered down, preventing damaging current backflow through the output pins into the Vcc rail.

Can this device be used for wired-logic?

Yes, the open-drain output can be connected to other open-drain outputs to implement active-low wired-OR or active-high wired-AND functions.
