SN74AHC125QDR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AHC125QDR is a quadruple bus buffer and line driver from Texas Instruments, belonging to the AHC logic series. It features four non-inverting channels with three-state outputs housed in a 14-pin SOIC package. The device operates within a supply voltage range of 2 V to 5.5 V, supporting low-power CMOS technology. Key electrical specifications include a maximum propagation delay of 11.5 ns at 3.3 V and output drive capabilities of ±8 mA. It functions reliably across an extended industrial temperature range from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific 'Q' suffix indicates automotive qualification status against the official datasheet. Confirm the package type matches design requirements. Ensure compliance with RoHS directives as specified by the manufacturer. Cross-reference the ordering part number with the manufacturer's current product selection guide to avoid obsolete variants.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple buffered signals with tri-state control on a shared bus. The AHC series offers speed comparable to ALVC while maintaining compatibility with standard CMOS levels. Consider the SOIC-14 package for surface-mount assembly constraints. Evaluate power consumption needs against the static current specifications provided in the electrical characteristics table.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the broader SN74AHC125 family of quadruple bus buffers. Variants exist in different packages such as TSSOP and VQFN, and with or without automotive qualification. The 'Q' designation typically aligns with automotive-grade reliability standards, distinguishing it from standard commercial grade parts within the same functional family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74AHC125DR (commercial grade) or SN74AHC125PWR (TSSOP package). Verify pinout compatibility and electrical parameters before substitution. Automotive applications may require specific qualified alternatives like the SN74AHC125QDRQ1.
