Overview
The TS5A3167DCKR is a single-channel, single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and features a maximum on-resistance of 900 mΩ. The device supports bidirectional signal transmission with a -3 dB bandwidth of 150 MHz and low charge injection of 6 pC. Switching times include a maximum turn-on time of 7 ns and a maximum turn-off time of 11.5 ns. It functions within an operating temperature range of -40°C to +85°C and is housed in a compact SC-70-5 surface-mount package.
Feature Summary
- Low on-resistance for minimal signal loss
- Bidirectional analog channel support
- Power-down mode isolation when VCC is zero
- Control inputs tolerant up to 5.5 V
Applications
- Portable audio applications
- Audio and video signal routing
- Low-voltage data acquisition systems
- Communication circuits
Procurement Notes
Verify the specific ordering suffix 'DCKR' against the manufacturer's current datasheet to confirm the SC-70-5 package and tape-and-reel packaging configuration. Ensure that the component meets RoHS3 compliance requirements if applicable to your manufacturing standards. Cross-reference the part number with official distributor catalogs to validate authenticity and traceability before procurement.
Selection Notes
Select this component for designs requiring a single SPST switch with low on-resistance under 1.65 V to 5.5 V supply conditions. It is suitable for space-constrained PCB layouts due to the SC-70-5 package. Consider the 150 MHz bandwidth and switching speeds when evaluating high-frequency signal integrity requirements compared to other family members.
Part Context
This part belongs to the TS5A3167 series of analog switches designed for portable electronics. It shares functional similarities with the TS5A3166 but differs in package type, offering the SC-70-5 form factor instead of SOT-23-5 variants. The series emphasizes low power consumption and high performance for battery-operated devices.
Replacement Considerations
The TS5A3167DBVR serves as a pin-compatible alternative within the same series, utilizing a SOT-23-5 package instead of SC-70-5. Verify footprint compatibility and thermal characteristics when substituting between these package types.
