Overview
The TS5A3159QDBVRQ1 is an automotive-grade, single-channel SPDT analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features a typical on-resistance of 1 Ω with excellent matching characteristics. The device supports bidirectional I/O signals ranging from 0 V to V+ and includes break-before-make switching to prevent signal distortion during channel transitions. It is qualified under AEC-Q100 standards for automotive applications and is housed in a compact SOT-23-6 package.
Feature Summary
- Break-before-make switching action prevents signal overlap between channels
- Low on-resistance ensures minimal signal attenuation
- Bidirectional signal transmission capability across the full supply range
- Automotive qualification for reliability in vehicle environments
Applications
- Portable audio equipment requiring low distortion
- Communication and network infrastructure systems
- Sensing and instrumentation circuits
- Test and measurement devices
Procurement Notes
Verify the specific suffix QDBVRQ1 against the official Texas Instruments datasheet to confirm automotive grade status and pinout compatibility. Ensure the component matches the required operating temperature range and voltage specifications for the target application before integration into production designs.
Selection Notes
Select this component when low total harmonic distortion and precise signal routing are critical. The 1 Ω on-resistance makes it suitable for high-fidelity audio paths. Verify that the control logic levels are compatible with the 5.5 V tolerant inputs to ensure reliable switching operation in the final system design.
Part Context
This part belongs to the TS5A3159 family of analog switches. The 'Q' prefix indicates automotive qualification, while 'DBVR' specifies the SOT-23-6 surface-mount package. It serves as a general-purpose multiplexer/demultiplexer solution for space-constrained electronic designs requiring high signal integrity.
Replacement Considerations
The TS5A3159ADCKR is a non-automotive variant with identical electrical performance but different packaging (SC-70). For direct functional replacement without automotive requirements, verify pin compatibility. No other cross-manufacturer substitutes are confirmed in public documentation.
