74AHC125D-Q100,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC125D-Q100,118 is a quad buffer and line driver featuring three-state outputs controlled by active LOW enable inputs. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an input voltage up to 5.5 V. The device is housed in a 14-lead SO14 plastic small outline package (SOT108-1). It is qualified to AEC-Q100 Grade 1 standards for automotive applications and functions reliably across an ambient temperature range of -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• Balanced propagation delays with Schmitt-trigger action on all inputs
• ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charge Device Model

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring high reliability
• Mixed voltage signal translation between different logic families
• High noise immunity data bus buffering
• Line driving in low power CMOS applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '118' corresponds to the standard tape and reel packaging configuration as defined in the ordering information table. Confirm that the SO14 package variant matches the required PCB footprint dimensions. Ensure design compliance with the specified thermal derating curves for total power dissipation at elevated temperatures above 100 °C.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when automotive grade certification is mandatory for the target application. Choose this part over non-automotive variants if extended temperature ranges up to +125 °C are required. Consider the overvoltage tolerant inputs for interfacing directly with higher voltage buses without external level shifting components.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Nexperia 74AHC125-Q100 family of quad buffers. It shares functional similarities with the 74AHCT125-Q100 but utilizes CMOS input levels rather than TTL levels. The D package variant specifically denotes the SO14 form factor, distinguishing it from TSSOP or DHVQFN options within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT125D-Q100,118 serves as a compatible alternative within the same family, differing primarily in input logic threshold specifications.
