Overview
The TS3A44159PWRG4 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. Key timing parameters include a maximum turn-on time of 23 ns and a maximum turn-off time of 32 ns. It is housed in a TSSOP-16 package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Quad SPDT configuration for multi-channel signal routing
- Low on-resistance for minimal signal attenuation
- Supports low-voltage single-supply operation
- High-speed switching with nanosecond transition times
Applications
- Portable audio equipment signal path switching
- Mobile phone camera module interface selection
- MP3 player and digital voice recorder input multiplexing
- Laptop computer peripheral connection management
Procurement Notes
Verify the specific suffix G4 indicates lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm the TSSOP-16 package dimensions match your PCB footprint requirements. Ensure the voltage supply rails remain strictly within the 1.65 V to 4.3 V operational limits to prevent device damage or performance degradation during integration.
Selection Notes
Select this component when a compact solution for four independent SPDT switches is required in space-constrained designs. It is suitable for applications demanding low power consumption and high bandwidth relative to other switches in its class. Consider the TSSOP-16 package availability if surface-mount assembly is preferred over larger packages like QFN.
Part Context
This part belongs to the TS3A44159 family of analog switches, designed primarily for portable consumer electronics. It serves as a low-cost alternative to discrete relay solutions, offering smaller form factors and lower power consumption. The PWRG4 designation specifically identifies the TSSOP-16 package variant with green molding compound and lead-free termination.
Replacement Considerations
The TS3A44159RGTR is a functional equivalent using a VQFN-16 package. Verify pinout compatibility before substitution. Other members of the TS3A series may offer different channel counts or package options but should be evaluated for identical electrical specifications.
