1P1G125QDCKRG4Q1

Overview

The SN74LVC1G125-Q1 is a single-channel, non-inverting buffer and line driver designed for automotive applications. It operates within a supply voltage range of 1.65 V to 5.5 V and features three-state outputs. The device is qualified under AEC-Q100 standards for Grade 1, supporting temperatures from -40°C to +125°C. Key electrical parameters include a propagation delay of 5.1 ns at 3.3 V and 4.1 ns at 5 V. Output drive capabilities are specified at ±24 mA, with a maximum static current of 10 µA. It is housed in a compact SC-70-5 package.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Single-channel non-inverting buffering with three-state output control for bus management.
• Wide operating voltage range supporting both low-voltage and standard 5 V logic systems.

Applications

• Automotive electronic control unit (ECU) signal buffering
• Portable equipment data transmission lines
• High-speed optical drives interface circuits

Procurement Notes

Verify the complete part number including the suffix 'G4Q1' to ensure correct RoHS compliance and automotive grade designation. Confirm the SC-70-5 package type matches your PCB footprint requirements. Check the specific revision level against your design documentation to ensure compatibility with existing firmware or hardware interfaces.

Selection Notes

Select this component when a single buffered channel with high drive strength is required in space-constrained automotive designs. The LVC series offers faster switching speeds compared to HC alternatives. Ensure the system voltage falls within the 1.65 V to 5.5 V range. Consider the SC-70-5 package size if board real estate is limited compared to larger packages like SOT-353.

Part Context

This part belongs to the Texas Instruments SN74LVC1G125 family of single-buffer line drivers. The 'Q1' suffix denotes automotive qualification, while 'G4' indicates lead-free and RoHS-compliant manufacturing. It serves as a fundamental building block for signal integrity management in digital circuits requiring isolation or amplification of logic levels.

Replacement Considerations

Direct functional substitutes within the same family include the 1P1G125QDCKRQ1. Verify pinout compatibility and electrical specifications before swapping between different manufacturer prefixes or suffixes that may indicate minor packaging or material differences.
