Overview
The TS3A44159RGTR is a quad single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65 V to 4.3 V. The device features a maximum on-resistance of 450 mOhms and supports a DC switch current of 100 mA. Key timing specifications include a maximum turn-on time of 23 ns and a maximum turn-off time of 32 ns. It is housed in a VQFN-16 package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent SPDT switches for signal routing
- Supports low-voltage operation down to 1.65 V
- Provides high bandwidth with fast switching speeds
Applications
- Portable multimedia devices requiring signal path switching
- Audio and video signal routing in consumer electronics
- Mobile phone peripheral interface management
Procurement Notes
Verify the specific suffix RGTR corresponds to the VQFN-16 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement specifications.
Selection Notes
Select this component when a quad SPDT configuration is required for low-voltage applications. Ensure the system voltage remains within the 1.65 V to 4.3 V range. Consider the 450 mOhm on-resistance for signal integrity requirements and verify that the VQFN-16 footprint fits the design constraints.
Part Context
This part belongs to the TS3A44159 series of analog switches. It shares functional similarities with other members like the TS3A44159PWR, differing primarily in package type. The series is designed for portable applications where space and power efficiency are critical constraints.
Replacement Considerations
The TS3A44159PWR is a pin-compatible alternative offering the same electrical characteristics in a TSSOP-16 package. Verify package dimensions and thermal performance differences before substitution.
