Overview
The TS5A3166YZPR is a dual single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V, supporting both 3.3-V and 5-V systems. The device features a low on-resistance of typically 0.9 ohms and an off-isolation of 60 dB at 1 MHz. It includes a charge pump that enables bidirectional signal transmission with rail-to-rail swing capability. The component is housed in an 8-pin DSBGA package and supports a continuous current of 200 mA.
Feature Summary
- Rail-to-rail signal handling via integrated charge pump for full voltage swing operation
- Bidirectional switching capability allowing flexible signal path configuration
- Low on-resistance ensuring minimal signal attenuation across the passband
- High off-isolation providing effective signal separation when deactivated
Applications
- Portable multimedia devices requiring signal routing between audio and video components
- Cellular phones for managing antenna switches and sensor interfaces
- MP3 players and portable media players for input/output selection
- Personal digital assistants (PDAs) for peripheral management
Procurement Notes
Verify the specific suffix YZPR against the manufacturer's official documentation to confirm the tape-and-reel packaging format and quantity per reel. Ensure the ordering information matches the exact part number variant required for the design, as suffixes may indicate differences in packaging or testing standards without altering the core electrical function.
Selection Notes
Select this component when designing circuits that require bidirectional analog switching with rail-to-rail signal integrity under low-voltage conditions. The integrated charge pump eliminates the need for external biasing voltages, simplifying the schematic. Verify that the operating temperature range and package thermal characteristics align with the system's environmental constraints and space limitations.
Part Context
This part belongs to the TS5A family of low-voltage analog switches from Texas Instruments. These devices are engineered for high performance in portable electronics where power efficiency and small form factors are critical. The family shares common architectural features such as charge pump technology and low on-resistance, tailored for applications like mobile phones and handheld computers.
Replacement Considerations
Publicly confirmed substitute part numbers for the TS5A3166YZPR were not identified in the provided reference material. Engineers should consult the manufacturer's official cross-reference tools or datasheet footnotes for verified alternatives.
