74LVC3G07DC,125

Overview

The Nexperia 74LVC3G07DC,125 is a triple non-inverting buffer with open-drain outputs housed in an 8-lead VSSOP package (SOT765-1). It operates within a supply voltage range of 1.65 V to 5.5 V and supports inputs up to 5.5 V. The device features Schmitt trigger inputs for noise immunity and IOFF circuitry for partial power-down applications. Propagation delay ranges from 0.5 ns to 8.4 ns depending on voltage. Output drive capability reaches -24 mA at 3.0 V. Operating temperature spans -40 °C to +125 °C.

Feature Summary

• Open-drain outputs enable active-LOW wired-OR or active-HIGH wired-AND logic functions.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow currents.
• Schmitt trigger inputs provide tolerance for slower input rise and fall times.

Applications

• Mixed 3.3 V and 5 V environments
• Partial power-down applications
• Wired-OR or wired-AND implementations

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74LVC3G07 family includes multiple variants such as TSSOP and XSON. Confirm that the DC suffix corresponds to the VSSOP8 package before finalizing procurement orders to ensure physical compatibility with the intended PCB footprint.

Selection Notes

Select this component when open-drain output configurations are required for bus sharing or level shifting between mixed voltage domains. The inclusion of Schmitt triggers makes it suitable for noisy environments or signals with slow transitions. Ensure the application does not require push-pull outputs, as this device only provides open-drain functionality.

Part Context

This part belongs to the 74LVC3G07 series of triple buffers with open-drain outputs. The 'DC' suffix specifically identifies the VSSOP8 plastic very thin shrink small outline package variant. Other available packages in this series include TSSOP8 and various XSON8 types, all sharing identical electrical characteristics but differing in physical dimensions.

Replacement Considerations

Direct substitutes within the same logical family include other 74LVC3G07 variants with different package suffixes, such as 74LVC3G07DP (TSSOP8) or 74LVC3G07GT (XSON8), provided the physical footprint allows for adaptation.

FAQ

Can the 74LVC3G07DC,125 be used for active-LOW wired-OR logic?

Yes, the open-drain outputs can be connected together to implement active-LOW wired-OR functions.

How does the IOFF circuitry function in this device?

The IOFF circuitry disables the output when the device is powered down, preventing potentially damaging backflow current through the device.
