74LVC125APW,118

Overview

The Nexperia 74LVC125APW,118 is a quad buffer and line driver featuring 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 supports overvoltage tolerant inputs up to 5.5 V. The device utilizes Schmitt-trigger action for noise immunity and includes IOFF circuitry for partial power-down applications. Packaged in a TSSOP14 (SOT402-1) format, it functions across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Provides four independent non-inverting buffers with 3-state outputs controlled by dedicated nOE pins.
• Features IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down states.
• Incorporates Schmitt-trigger inputs to ensure tolerance against slow input rise and fall times.

Applications

• Translating signals between mixed 3.3 V and 5 V logic environments
• Driving high-capacitance or resistive loads on transmission lines
• Isolating data buses via high-impedance OFF-states

Procurement Notes

Verify the specific ordering suffix ',118' matches the required tape-and-reel packaging configuration. Confirm the package designation SOT402-1 corresponds to the intended TSSOP14 footprint. Ensure the component status aligns with long-term availability requirements as product lifecycles may change.

Selection Notes

Select this component when a quad buffer with 3-state control is required for low-voltage CMOS logic systems. The wide supply range accommodates various standard logic families. Verify that the operating temperature range meets the environmental constraints of the target application.

Part Context

This part belongs to the 74LVC125A family of quad bus buffers manufactured by Nexperia. The 'APW' designation identifies the TSSOP14 plastic thin shrink small outline package variant. The suffix ',118' indicates the specific reel quantity and packaging method provided by the manufacturer.

Replacement Considerations

Direct functional equivalents include other 74LVC125 variants from different manufacturers, such as the SN74LVC125A series. Cross-reference pinouts and electrical characteristics to ensure compatibility with existing designs.
