Overview
The TS5A3166DCKRG4 is a single-channel, normally-open SPST analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65 V to 5.5 V. The device features a maximum on-resistance of 900 mOhms and supports a continuous DC switch current of 100 mA. Switching performance includes a maximum turn-on time of 7 ns and a maximum turn-off time of 11.5 ns. It is housed in a SC70-5 surface-mount package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Single-channel SPST configuration with normally-open logic
- Low on-resistance for minimal signal attenuation
- Capable of handling high continuous DC switch currents
- Fast switching speeds suitable for dynamic signal routing
Applications
- Signal path selection in portable electronic devices
- Audio and video signal routing in consumer electronics
- Battery-powered equipment requiring low power consumption
- Communication systems utilizing single-supply operation
Procurement Notes
Verify the component against official Texas Instruments documentation to confirm specifications and authenticity. Ensure the SC70-5 package matches design requirements. Check for RoHS compliance status as indicated in the datasheet. Confirm that the operating temperature range meets environmental constraints. Validate pinout compatibility before integration into the circuit layout.
Selection Notes
Select this component when a single-pole single-throw switch is required for signals up to 5.5 V. The low on-resistance makes it suitable for applications where signal integrity is critical. Consider the SC70-5 package size for space-constrained designs. Ensure the control logic levels are compatible with the 1.65 V to 5.5 V supply range.
Part Context
This part belongs to the TS5A3166 family of analog switches. It shares core electrical characteristics with variants like the TS5A3166DCKR but may differ in packaging or manufacturing revisions. The 'G4' suffix typically denotes lead-free and RoHS-compliant construction according to Texas Instruments naming conventions.
Replacement Considerations
The TS5A3166DCKR is a functional equivalent within the same family. For automotive applications, the TS5A3166QDCKRQ1 offers AEC-Q100 qualification. Other single-channel options include the TS5A3167, which provides a normally-closed configuration.
