74AHC125PW,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC125PW,118 is a quad buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 5.5 V and utilizes a TSSOP14 package (SOT402-1). The device provides balanced propagation delays and includes Schmitt-trigger action on all inputs for high noise immunity. Inputs are overvoltage tolerant up to 5.5 V, allowing use in mixed-voltage environments.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Quad non-inverting buffer/line driver with three-state outputs
• Overvoltage tolerant inputs compatible with mixed voltage systems
• Schmitt-trigger inputs provide enhanced noise immunity
• Balanced propagation delays across all channels

Buffers, Drivers, Receivers, Transceivers Applications

• Translating signals between different voltage domains
• Driving bus lines requiring three-state control
• Buffering digital signals in mixed-voltage circuitry

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix ',118' corresponds to the TSSOP14 package variant when sourcing. Confirm that the required logic family matches the AHC specification rather than AHCT, as input thresholds differ significantly between CMOS and TTL levels. Ensure the application environment remains within the specified temperature range of -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when four independent buffers with tri-state capability are required in a compact surface-mount package. The AHC series offers lower power consumption compared to older logic families while maintaining high-speed performance. Verify that the system's maximum input voltage does not exceed the 5.5 V tolerance limit of the inputs.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC logic family, which represents high-speed CMOS technology. It is functionally similar to the 74AHCT125 but differs in input threshold characteristics, supporting full CMOS input levels rather than TTL-specific levels. The PW suffix indicates the thin shrink small outline plastic package.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT125PW,118 serves as a direct pin-compatible alternative if TTL-level input compatibility is required instead of CMOS levels. Other variants such as the SO14 package version (74AHC125D) offer identical electrical specifications with a different physical footprint.
