Overview
The TS5A3166QDCKRQ1 is a single-channel SPST analog switch from Texas Instruments, designed for automotive applications under AEC-Q100 qualification. It operates on a single supply voltage ranging from 1.65 V to 5.5 V. Key electrical parameters include a maximum on-resistance of 900 mOhms and a maximum power supply current of 100 nA. The device supports a DC switch current of 100 mA. Timing characteristics feature a maximum turn-on time of 7 ns and a maximum turn-off time of 11.5 ns. It functions within an extended temperature range of -40°C to +125°C and is housed in a SC70-5 surface-mount package.
Feature Summary
- Automotive-grade reliability certified by AEC-Q100 standards
- Ultra-low quiescent current consumption for power-sensitive designs
- High-speed signal switching with nanosecond transition times
- Wide operating voltage compatibility with low-voltage logic
Applications
- Automotive infotainment system signal routing
- Instrument cluster sensor multiplexing
- Body control module peripheral selection
Procurement Notes
Verify the specific suffix Q1 confirms AEC-Q100 automotive qualification status against the manufacturer's official documentation. Confirm the DCKR package designation matches the required SC70-5 footprint and reel specifications for your assembly line. Ensure the component version aligns with current production status to avoid obsolescence risks during long-term manufacturing cycles.
Selection Notes
Select this component when a single-pole single-throw configuration is required for low-voltage analog signal paths. The wide input voltage range allows direct interfacing with both 3.3-V and 5-V systems without level shifting. Consider the low on-resistance for minimal signal attenuation in precision measurement circuits requiring high fidelity transmission.
Part Context
This part belongs to the TS5A3166 series of single-channel analog switches. It shares core functional specifications with non-automotive variants like the TS5A3166DCKRE4, but differs in qualification standards and extended temperature rating. The series provides compact solutions for space-constrained PCB layouts requiring reliable signal isolation.
Replacement Considerations
The TS5A3166DCKRE4 is a documented alternative within the same family. Note that the standard variant typically has a lower maximum operating temperature of +85°C compared to the Q1 automotive grade. Verify pinout compatibility and package dimensions before substituting to ensure mechanical fit.
