Overview
The TS3A44159RSVR is a quad single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It features four independent channels with a maximum on-resistance of 0.45 ohms and supports a supply voltage range from 1.65 V to 4.3 V. The device operates within a temperature range of -40°C to +85°C and utilizes a 16-pin VQFN package. Key electrical specifications include a maximum operating time of 23 ns, an off-time of 32 ns, and a maximum quiescent current of 700 nA. It functions as a multiplexer or demultiplexer controlled by two logic inputs.
Feature Summary
- Quad SPDT configuration for signal routing
- Low on-resistance for minimal signal loss
- Single-supply operation compatible with low-voltage systems
Applications
- Audio and video signal switching
- Portable consumer electronics
- Mobile phone peripheral management
Procurement Notes
Verify the specific suffix RSVR against the official datasheet to confirm the package type and tape-and-reel specifications. Ensure the component matches the required thermal and electrical ratings for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when a quad-channel SPDT switch is required with low on-resistance and single-supply compatibility. Compare against similar parts like the TS3A44159PWR if different packaging options are needed while maintaining identical electrical performance characteristics.
Part Context
This part belongs to the TS3A44159 series of analog switches designed for portable applications. It offers high integration by providing four independent switches in a compact footprint, suitable for space-constrained designs requiring efficient signal path management.
Replacement Considerations
The TS3A44159PWR is a verified alternative offering identical electrical specifications but housed in a TSSOP-16 package instead of the VQFN-16 format used by the RSVR variant.
