Overview
The TS3A44159PWR 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 switch DC current of 100 mA. Electrical performance includes a maximum turn-on time of 23 ns and a maximum turn-off time of 32 ns. The component functions within an operating temperature range of -40°C to +85°C. It is housed in a TSSOP-16 surface-mount package.
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 times
Applications
- Audio and video signal path switching
- Portable consumer electronics
- Mobile phone peripheral interfacing
Procurement Notes
Verify the specific suffix PWR indicates the TSSOP-16 package and tape-and-reel shipping configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement specifications.
Selection Notes
Select this component when designing circuits requiring multiple signal paths within a compact footprint. Ensure the input signal levels remain within the absolute maximum ratings relative to the selected supply voltage. Verify that the load current requirements do not exceed the specified 100 mA limit per channel.
Part Context
This part belongs to the TS3A44159 family of analog switches. Other variants in the series include the TS3A44159RGTR, which utilizes a VQFN-16 package instead of the TSSOP-16 form factor found in the PWR version. Both share identical electrical characteristics and functional configurations.
Replacement Considerations
The TS3A44159RGTR serves as a direct functional substitute with identical electrical parameters, differing only in the VQFN-16 package style. Designers must adjust PCB layout footprints accordingly when substituting between these package types.
