Overview
The TS5A3166DCKR is a single-channel SPST analog switch manufactured by Texas Instruments, designed for low-voltage applications. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum on-resistance of 900 mOhms. The device supports a continuous DC switch current of 100 mA with a maximum power consumption of 800 nA. Key timing parameters include a maximum turn-on time of 7 ns and a maximum turn-off time of 11.5 ns. It functions reliably across an operating temperature range from -40°C to +85°C and is housed in a compact SC-70-5 surface-mount package.
Feature Summary
- Single-pole single-throw (SPST) configuration providing one independent signal path
- Low on-resistance characteristic ensuring minimal signal attenuation
- Wide single-supply voltage compatibility for diverse logic levels
- High-speed switching performance suitable for dynamic signal routing
Applications
- Portable audio equipment signal routing
- Battery-powered consumer electronics
- Communication and networking signal paths
- Sensor and instrumentation signal conditioning
Procurement Notes
Verify the specific ordering suffix DCKR to confirm the SC-70-5 package type and tape-and-reel shipping format. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the standard industrial temperature range aligns with your environmental specifications before finalizing procurement orders.
Selection Notes
Select this component when a single analog channel requires low distortion and fast switching within a 1.65 V to 5.5 V system. Compare against the TS5A3166QDCKRQ1 if automotive qualification under AEC-Q100 standards is required. Consider the TS5A3159 if a single-pole double-throw (SPDT) configuration or break-before-make functionality is necessary instead of simple SPST switching.
Part Context
This part belongs to the TS5A3166 series of low-voltage analog switches from Texas Instruments. It shares core electrical characteristics with variants such as the TS5A3166DCKRG4, differing primarily in manufacturing lot or packaging details. The series is engineered for portable devices where space constraints and power efficiency are critical design factors.
Replacement Considerations
The TS5A3166DCKJ is listed as a discontinued equivalent with similar SPDT characteristics but different pinout and package geometry. Direct pin-to-pin replacement requires verification of package dimensions and control logic compatibility.
