Overview
The TS5A3167DBVRG4 is a single-channel, 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 and features a maximum on-resistance of 900 mΩ. The device supports bidirectional signal flow with a maximum DC current of 100 mA. Key electrical parameters include a maximum power supply current of 100 nA, an on-time of 7 ns, and an off-time of 11.5 ns. It is housed in a SOT-23-5 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides high isolation when powered down with VCC at 0 V
- Features low charge injection for improved signal integrity
- Control inputs tolerate up to 5.5 V regardless of supply voltage
- Exhibits excellent total harmonic distortion performance
Applications
- Portable audio applications
- Audio and video signal routing
- Low-voltage data acquisition systems
- Mobile phones and personal digital assistants
Procurement Notes
Verify the specific suffix G4 indicates lead-free compliance and RoHS standards before procurement. Confirm the component status as End-of-Life or obsolete through official Texas Instruments channels to ensure long-term availability. Validate that the SOT-23-5 package matches the target PCB footprint requirements. Check for any recent Product Change Notifications regarding assembly sites or marking changes.
Selection Notes
Select this component for designs requiring a single SPST switch with low on-resistance in compact spaces. Ensure the application voltage stays within the 1.65 V to 5.5 V range. Consider the 7 ns switching speed for timing-critical signals. Verify that the 100 nA quiescent current meets system power constraints. Compare against the TS5A3167DCKR if a SC-70-5 package is preferred instead of SOT-23-5.
Part Context
This part belongs to the TS5A3167 family of analog switches from Texas Instruments. It shares core specifications with variants like the TS5A3167DBVR but differs in packaging and compliance markings. The DBVR designation specifically identifies the SOT-23-5 surface-mount package configuration used in space-constrained portable electronics.
Replacement Considerations
The TS5A3167DBVR is the non-RoHS compliant predecessor. The TS5A3167DCKR offers identical electrical performance but utilizes a SC-70-5 package. Verify pinout compatibility when substituting these alternatives.
