SN74LV4T125QPWRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV4T125QPWRQ1 is an automotive-grade quadruple buffer translator with 3-state outputs. It operates on a single supply voltage ranging from 1.6 V to 5.5 V, supporting level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V CMOS levels. The device features 5.5-V tolerant input pins for down-translation and reduced input thresholds for up-translation. It provides balanced CMOS outputs capable of driving up to ±25 mA at 3.3 V to 5.0 V. The component meets AEC-Q100 Grade 1 standards, ensuring reliability across a temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel specifications. Confirm the device grade aligns with the target automotive application requirements. Ensure compatibility with the intended operating voltage range and thermal management constraints before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional level shifting between disparate voltage domains is required within an automotive system. The LVxT family architecture allows flexible configuration for both stepping up and stepping down logic levels using a single power rail. Consider the 3-state output functionality if bus sharing or signal gating is necessary for the design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV4T125-Q1 series, which is designed for low-voltage CMOS applications requiring robust signal integrity. The 'Q1' designation indicates qualification for automotive use, while the 'PWR' suffix specifies the TSSOP-14 package format. It serves as a bridge between legacy 5-V systems and modern lower-voltage microcontrollers.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74LV4T125RGYR for alternative packaging options within the same functional family. Verify SN74LV4T125PW for standard industrial-grade equivalents if automotive certification is not strictly required. Ensure any substitute maintains the 3-state output and voltage translation capabilities.
