74LVC3G07V8-7

Overview

The 74LVC3G07V8-7 is a triple buffer with open-drain outputs manufactured by Diodes Incorporated. It operates within a supply voltage 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 I_OFF circuitry, which disables outputs to prevent damaging current backflow. It provides an output drive of -24mA at 3.3V and includes ESD protection exceeding 2,000V (HBM) and 1,000V (CDM). Propagation delay ranges from 1ns to 8.3ns depending on voltage and temperature.

Feature Summary

• Triple non-inverting buffers with open-drain outputs requiring external pullup resistors
• IOFF circuitry enables safe partial power down mode operation
• Inputs accept up to 5.5V for compatibility in mixed-voltage systems
• High ESD protection ratings per JESD 22 standards

Applications

• Voltage-level shifting between different logic families
• Power down signal isolation
• General-purpose logic buffering
• PCs, networking equipment, and computer peripherals
• Portable devices such as cell phones and MP3 players

Procurement Notes

Verify the specific V8 package code corresponds to the required VSSOP-8 footprint and pinout dimensions. Confirm that the datasheet revision matches the design requirements, particularly regarding thermal resistance values and operating temperature limits. Ensure the ordering suffix indicates the correct tape and reel quantity for the manufacturing process.

Selection Notes

Select this component when open-drain outputs are necessary for wired-AND configurations or level translation. The wide supply voltage range allows flexibility across various digital systems. Verify that the input tolerance meets the driving source voltage levels. Consider the propagation delay specifications relative to the system clock speeds to ensure timing compliance.

Part Context

This part belongs to the 74LVC series of low-voltage CMOS logic devices. It is functionally similar to other triple buffers but distinguished by its open-drain output structure. The V8 suffix specifically denotes the VSSOP-8 surface-mount package variant offered by Diodes Incorporated.

Replacement Considerations

Check for direct equivalents like the 74LVC3G07SS8-7 if SSOP-8 packaging is acceptable. Verify pin compatibility and electrical characteristics against other LVC family parts before substitution.

FAQ

Why is a pullup resistor required for this device?

The 74LVC3G07V8-7 features open-drain outputs, which can only sink current to ground. A pullup resistor is necessary to provide a logical HIGH state.

How does the IOFF feature benefit the circuit?

The IOFF circuitry disables the outputs when the device is powered down, preventing damaging current backflow from powered buses into the unpowered device.
