74LVC1G07GX,125

Overview

The Nexperia 74LVC1G07GX,125 is a single buffer with open-drain output in the LVC logic series. It operates within a supply voltage range of 1.65 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device supports partial power-down via IOFF circuitry and provides -24 mA output drive at VCC = 3.0 V. It is housed in an X2SON5 package (SOT1226-3) with dimensions of 0.8 mm x 0.8 mm x 0.32 mm. Operating temperatures range from -40 °C to +125 °C.

Feature Summary

• Open-drain output configuration allows level translation between mixed voltage domains.
• Schmitt-trigger inputs provide tolerance for slow input rise and fall times.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current.

Applications

• Level shifting between 3.3 V and 5 V devices
• Partial power-down applications requiring backflow current prevention
• Mixed voltage environment signal buffering

Procurement Notes

Verify the specific ordering suffix GX,125 corresponds to the X2SON5 (SOT1226-3) package variant. Confirm that the required operating temperature range includes the extended upper limit of +125 °C specified for this part number. Ensure design compatibility with the open-drain output topology and external pull-up requirements.

Selection Notes

Select this component when a single-channel non-inverting buffer with open-drain capability is required. The X2SON5 package offers a compact footprint suitable for space-constrained designs. Verify that the application benefits from Schmitt-trigger input characteristics and that the -24 mA drive current meets load requirements.

Part Context

This component belongs to the 74LVC1G07 family of single buffers with open-drain outputs. The 'GX' suffix specifically identifies the X2SON5 plastic thermal enhanced extremely thin small outline package. This package variant distinguishes it from other options like TSSOP5 or SC-74A within the same logical function family.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include Diodes Incorporated 74LVC1G07FS3-7 and Texas Instruments SN74LVC1G07DPWR. Verify pinout and package compatibility before substitution.

FAQ

What is the function of the IOFF circuitry in this device?

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

Does the 74LVC1G07GX have Schmitt-trigger inputs?

Yes, the device features Schmitt-trigger action at all inputs, making it tolerant of slower input rise and fall times.
