74LVC125APW,112

Overview

The Nexperia 74LVC125APW,112 is a quad buffer/line driver with 3-state outputs controlled by active LOW output enable inputs (nOE). It operates within a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device utilizes Schmitt-trigger action for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down states. It is housed in a TSSOP14 package (SOT402-1) and supports operation from -40 °C to +125 °C.

Feature Summary

• Provides 3-state buffering with high-impedance OFF-states when nOE is HIGH
• Features Schmitt-trigger inputs to tolerate slow rise and fall times
• Includes IOFF circuitry to disable outputs and prevent damaging backflow currents during power-down
• Supports direct interface with TTL levels and mixed 3.3 V/5 V environments

Applications

• Translating signals between mixed 3.3 V and 5 V logic environments
• Driving bus lines or external loads requiring 3-state control
• Partial power-down applications where backflow protection is required

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component for designs requiring quad buffering with 5 V tolerance on a 1.2 V to 3.6 V supply. Ensure the application benefits from Schmitt-trigger input hysteresis and requires IOFF functionality for safe partial power-down operation. Confirm that the TSSOP14 package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the 74LVC125A family of quad buffers/line drivers. The APW suffix specifically denotes the TSSOP14 plastic thin shrink small outline package (SOT402-1). Other variants in the family include SO14, DHVQFN14, and DHXQFN14 packages, offering flexibility for different space and thermal requirements.

Replacement Considerations

Direct replacements must match the 74LVC125A function, TSSOP14 package, and 5 V tolerance. Verify if automotive qualification (e.g., 74LVC125AD-Q100J) is required, as standard and qualified versions may differ in reliability specifications despite identical electrical performance.
