1P1G125QDCKRQ1

Overview

The 1P1G125QDCKRQ1 is an automotive-grade single bus buffer gate with three-state output, belonging to the SN74LVC1G125-Q1 series. It operates within a supply voltage range of 1.65 V to 5.5 V and features non-inverting logic. The device provides high-level output current of -24 mA and low-level output current of 24 mA, with a static current of 10 uA. Propagation delay is specified at 5.1 ns at 3.3 V and 4.1 ns at 5 V. It is housed in a SC70-5 package and supports surface mount installation across a temperature range of -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments
• Three-state output capability enables effective bus line isolation and signal management
• Wide operating voltage range supports compatibility with various digital logic families

Applications

• Automotive electronic control unit signal buffering

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number and date code against official Texas Instruments documentation. Ensure the specific suffix matches the required automotive grade and packaging configuration. Confirm compliance with RoHS directives and check for any recent product change notices that may affect pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring a single-channel buffer with high drive strength and low quiescent current. The LVC logic family offers fast switching speeds suitable for high-frequency data transmission. Consider the SC70-5 package size for space-constrained PCB layouts. Ensure the input voltage levels are compatible with the chosen supply voltage to maintain proper logic threshold margins during operation.

Part Context

This device is part of the SN74LVC1G125-Q1 family of single bus buffers designed specifically for automotive applications. It shares functional similarities with other LVC series components but includes specific automotive reliability testing. The Q1 designation indicates adherence to automotive quality standards, distinguishing it from standard commercial grade counterparts while maintaining similar electrical performance profiles.

Replacement Considerations

Direct substitutes include SN74LVC1G125QDCKRQ1 and SN74LVC1G125QDBVRQ1. Verify package compatibility and ensure the replacement maintains AEC-Q100 certification if automotive usage is required.
