Overview
The TS3A44159RGTRG4 is a quad single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It integrates four independent channels within a VQFN-16 package, supporting a supply voltage range of 1.65 V to 4.3 V. The device features a maximum on-resistance of 0.45 ohms and supports a continuous DC current of 100 mA per channel. Key electrical parameters include a maximum operating frequency of 23 ns for turn-on time and 32 ns for turn-off time. It operates reliably across an extended temperature range from -40°C to +85°C with a maximum quiescent current of 700 nA.
Feature Summary
- Quad SPDT configuration enabling two-channel multiplexer or demultiplexer functionality using only two control signals.
- Low on-resistance characteristic ensures minimal signal attenuation in high-fidelity audio and video paths.
- Ultra-low power consumption design suitable for battery-operated portable devices.
Applications
- Audio switching in mobile phones and portable media players.
- Video signal routing in handheld devices and tablets.
- Cellular phone antenna switching modules.
- Portable gaming consoles requiring low-latency signal path selection.
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm compliance with lead-free and RoHS standards. Ensure the VQFN-16 package type matches the target PCB footprint requirements. Confirm that the reel packaging aligns with automated assembly line specifications before finalizing procurement orders.
Selection Notes
Select this component when a compact solution for routing multiple analog signals is required. The dual-control architecture simplifies logic design compared to individual switches. Verify that the 4.3 V maximum supply voltage meets system constraints. Consider thermal dissipation capabilities if operating near the upper limits of the specified current ratings.
Part Context
This part belongs to the TS3A44159 series of analog switches designed for space-constrained applications. It serves as a direct replacement for previous generations of quad SPDT switches, offering improved performance metrics in a smaller footprint. The series is widely utilized in consumer electronics where signal integrity and power efficiency are critical design parameters.
Replacement Considerations
The TS3A44159PWRG4 offers identical electrical characteristics but utilizes a TSSOP-16 package instead of VQFN-16. Verify pin-to-pin compatibility and thermal pad requirements before substituting packages. Other family members may share functional similarities but differ in channel count or package style.
