Overview
The TS3A24157RSER is a dual single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and features a maximum on-resistance of 650 mOhms. The device is housed in a UQFN-10 surface-mount package and supports bidirectional signal transmission. Designed for low-power applications, it includes an active pull-down circuit to ensure defined output states during power-off conditions.
Feature Summary
- Dual SPDT configuration enabling multiplexing or demultiplexing functions
- Low on-resistance for minimal signal attenuation
- Active pull-down mechanism for stable power-off state management
Applications
- Portable multimedia devices requiring signal routing
- Audio switching circuits in mobile handsets
- Video signal path selection in compact electronics
Procurement Notes
Verify the specific suffix RSER against official datasheets to confirm the UQFN-10 package type and reel packaging format. Ensure compatibility with the target operating voltage range of 1.65 V to 3.6 V before integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability.
Selection Notes
Select this component when a dual-channel SPDT switch is required for low-voltage digital or analog signals. The UQFN-10 package suits space-constrained designs. Compare the 650 mOhm on-resistance against application requirements to ensure acceptable signal loss. Verify that the 3.6 V maximum supply voltage aligns with the system power rails.
Part Context
This part belongs to the TS3A2415x family of analog switches from Texas Instruments. The series provides multiple package options including MSOP and UQFN variants. These components are engineered for portable consumer electronics where low power consumption and small footprint are critical design constraints.
Replacement Considerations
The TS3A24157DGSR serves as a pin-compatible alternative featuring an MSOP-10 package instead of UQFN-10. Both parts share identical electrical specifications and functionality. Verify package dimensions and thermal characteristics when substituting.
