74LVC3G07GD,125

Overview

The Nexperia 74LVC3G07GD,125 is a triple non-inverting buffer with open-drain outputs housed in an XSON8 package (SOT1203). 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 protection. Static characteristics include a maximum low-level output voltage of 0.80 V at 24 mA drive current. Dynamic performance specifies propagation delays ranging from 0.5 ns to 5.5 ns depending on voltage.

Feature Summary

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

Applications

• Mixed 3.3 V and 5 V logic environments
• Wired-OR or wired-AND bus implementations
• Partial power-down system designs

Procurement Notes

Verify the specific ordering suffix GD corresponds to the SOT1203 XSON8 package variant. Confirm that the required operating temperature range aligns with the -40 °C to +125 °C specification provided in the datasheet. Ensure design compatibility with the open-drain output topology rather than push-pull configurations.

Selection Notes

Select this component when open-drain output capability is required for wired logic connections. The wide supply voltage range allows operation across multiple logic families. Verify that the load capacitance and pull-up resistor values are compatible with the specified transition rates and propagation delay requirements.

Part Context

This part belongs to the 74LVC3G07 family of triple buffers with open-drain outputs. The GD suffix identifies the specific XSON8 plastic extremely thin small outline package (SOT1203) variant. Other variants in the series utilize different packages such as TSSOP8 or VSSOP8.

FAQ

How does the IOFF circuitry function?

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

What logic functions can be implemented using the outputs?

The open-drain outputs can be connected together to implement active-LOW wired-OR or active-HIGH wired-AND functions.
