74LVC125APW/C5J

Overview

The Nexperia 74LVC125APW/C5J is a quad buffer and line driver featuring 3-state outputs controlled by active LOW enable inputs (nOE). It operates within a supply voltage range of 1.2 V to 3.6 V, with overvoltage tolerant inputs up to 5.5 V. The device incorporates Schmitt-trigger action for noise immunity and IOFF circuitry to prevent backflow current during partial power-down. It is housed in a TSSOP14 package (SOT402-1) and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Quad buffer/line driver with 3-state outputs
• Overvoltage tolerant inputs up to 5.5 V
• IOFF circuitry for partial power-down protection
• Schmitt-trigger inputs for slow signal tolerance

Applications

• Mixed 3.3 V and 5 V translation environments
• Partial power-down applications requiring backflow prevention
• Line driving with high noise immunity requirements

Procurement Notes

Verify the specific suffix /C5J against official Nexperia documentation to confirm tape-and-reel packaging specifications and marking details. Ensure the ordering code matches the required TSSOP14 variant. Confirm compliance with RoHS3 standards and check for any recent Product Change Notifications affecting assembly or labeling.

Selection Notes

Select this component when interfacing between 3.3 V and 5 V logic domains is required. The wide supply range and input tolerance make it suitable for mixed-voltage systems. Verify that the TSSOP14 package dimensions fit the PCB layout constraints and that the thermal dissipation capabilities are sufficient for the application's power budget.

Part Context

This part belongs to the 74LVC125A family of quad buffers. It shares functional characteristics with other variants like the 74LVC125AD (SO14) and 74LVC125ABQ (DHVQFN14), differing primarily in package type and pin configuration. All variants offer identical electrical performance regarding voltage tolerance and drive capability.

Replacement Considerations

Direct substitutes include 74LVC125AD (SO14 package) and 74LVC125ABQ (DHVQFN14 package) from Nexperia. Cross-manufacturer replacements must match the quad buffer function, 3-state output, and 5 V input tolerance specifications.
