Overview
The TS5A3166DBVRE4 is a single-channel, 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. The component is housed in a SOT-23-5 surface-mount package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Single-pole single-throw (SPST) configuration for signal path control
- Low on-resistance for minimal signal attenuation
- Compatible with low-voltage logic interfaces
Applications
- Portable equipment power management
- Sensor multiplexing circuits
- Audio and video signal switching
Procurement Notes
Verify the E4 suffix indicates lead-free compliance and RoHS standards. Confirm the DBVR package variant matches design requirements. Check manufacturer lifecycle status as end-of-life notices may affect long-term availability. Validate authenticity through authorized distribution channels to avoid counterfeit components.
Selection Notes
Select this part for applications requiring a single analog channel with low on-resistance. Ensure the input signal remains within the 1.65 V to 5.5 V supply range. Consider charge injection effects if used in high-precision ADC front ends. Verify thermal dissipation capabilities within the specified operating temperature range.
Part Context
This component belongs to the TS5A316x series of analog switches from Texas Instruments. It shares functional similarities with the TS5A3167 but differs in pinout or specific electrical characteristics. The series is designed for cost-sensitive portable devices requiring efficient signal routing.
Replacement Considerations
The TS5A3166DCKRE4 serves as a direct alternative with identical electrical specifications but utilizes an SC-70-5 package instead of SOT-23-5. Verify footprint compatibility before substitution.
