Overview
The TS5A3167DBVRE4 is a single-channel, single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and is housed in a SOT-23-5 surface-mount package. The device features a maximum on-resistance of 900 mOhms and supports a DC switch current of 100 mA. 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 of -40°C to +85°C with a maximum supply current of 100 nA.
Feature Summary
- Provides bidirectional analog signal routing with low on-resistance for minimal signal loss.
- Ensures high isolation in power-down mode when the supply voltage is zero.
- Features control inputs tolerant up to 5.5 V for flexible logic interfacing.
- Delivers low charge injection and total harmonic distortion suitable for audio applications.
Applications
- Audio and video signal routing in portable devices
- Mobile phone and personal digital assistant circuitry
- Low-voltage data acquisition systems
- Modems and hard disk drive interfaces
Procurement Notes
Verify the specific suffix E4 against the manufacturer's latest documentation to confirm compliance status and material composition changes. Confirm end-of-life status as distribution sources indicate potential obsolescence. Ensure the SOT-23-5 package variant matches the design footprint requirements before finalizing procurement orders.
Selection Notes
Select this component for designs requiring a single SPST switch with low on-resistance under 1.65 V to 5.5 V supplies. Consider the SOT-23-5 package size constraints and the -40°C to +85°C industrial temperature range. Verify that the 100 mA DC switch current meets the load requirements and that the 7 ns switching speed aligns with system timing needs.
Part Context
This part belongs to the TS5A3167 series of low-power analog switches from Texas Instruments. It shares core electrical characteristics with variants like the TS5A3167DBVR but differs in packaging configuration or compliance markings defined by the E4 suffix. The series is designed for portable electronics where power consumption and signal integrity are critical.
Replacement Considerations
The TS5A3167DBVRG4 is a documented alternative within the same family. Verify pinout compatibility and ensure the replacement maintains the required SOT-23-5 form factor and electrical specifications for direct substitution.
