Overview
The TS5A9411DCKR is a single-channel, 10-ohm SPDT analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and features low on-resistance for signal integrity. The device supports bidirectional signal flow and includes an active pull-down circuit to ensure defined states during power-up or shutdown conditions. Packaged in a compact SC70-5 (SOT-353) surface-mount case, it is designed for portable applications requiring minimal board space.
Feature Summary
- Single-pole double-throw (SPDT) configuration enabling 2:1 multiplexer or demultiplexer functionality
- Low on-resistance of 10 ohms ensures minimal signal attenuation across the operating range
- Integrated active pull-down circuit maintains defined output states during power transitions
- Bidirectional switching capability allows flexible signal routing in compact designs
Applications
- Portable audio equipment such as headphones and mobile devices
- Cellular phones and handheld communication devices
- MP3 players and digital media controllers
- Personal navigation systems (PNDs)
- Digital still cameras and camcorders
Procurement Notes
Verify the component authenticity by checking the manufacturer's marking code against official documentation. Ensure the SC70-5 package matches the required footprint for PCB layout. Confirm that the supply voltage requirements align with the system design before integration. Request the latest datasheet revision to verify any updates to electrical characteristics or recommended operating conditions.
Selection Notes
Select this component when a single-channel SPDT switch is required within a 1.65 V to 5.5 V supply range. The 10-ohm on-resistance is suitable for general-purpose analog signal routing where low distortion is needed. Consider the SC70-5 package size if board space is constrained. Verify that the input signal levels remain within the specified limits relative to the supply voltage to prevent damage.
Part Context
The TS5A9411 belongs to Texas Instruments' TS5A series of low-voltage analog switches. This family is optimized for portable electronics due to its small footprint and low power consumption. The DCKR suffix indicates the specific SC70-5 package variant with reel packaging, distinguishing it from other pin configurations or tape-and-reel options available in the broader product line.
Replacement Considerations
Direct replacements include the TS5A9411DCKT (cut tape version) or TS5A9411DCKRG4 (RoHS-compliant variant). Other compatible parts may include the TS3A24157 for dual-channel needs, though pinouts and specifications differ. Always verify electrical parameters and package dimensions before substituting.
