Overview
The TS5A3159DBVR is a single-channel, single-pole double-throw (SPDT) 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 1.1 Ohms. The device supports bidirectional signal transmission from 0 V to V+ with low distortion characteristics. Key electrical parameters include a maximum propagation delay of 35 ns and an off-time of 20 ns. It functions in temperatures ranging from -40°C to +85°C and draws a maximum supply current of 100 nA. The component is housed in a SOT-23-6 surface-mount package.
Feature Summary
- Provides break-before-make switching action to prevent signal distortion during channel transitions
- Supports 5.5 V tolerant control inputs for compatibility with various logic levels
- Offers high isolation in power-down mode when the supply voltage is zero
- Delivers low charge injection and excellent on-resistance matching for minimal signal distortion
Applications
- Portable audio equipment requiring low total harmonic distortion
- Battery-powered consumer electronics and portable instruments
- Signal routing in communication and networking systems
- Test and measurement instrumentation circuits
Procurement Notes
Verify the specific suffix DBVR indicates the reel packaging format as documented in official distributor catalogs. Confirm RoHS compliance status through the manufacturer's current datasheet or certification documents. Ensure the ordering part number matches the exact pin configuration and thermal specifications required for the target PCB layout design.
Selection Notes
Select this component for applications requiring a single SPDT switch with low on-resistance under 1.1 Ohms. It is suitable for signals swinging between ground and the positive supply rail. Consider the SOT-23-6 package constraints for space-limited designs. Verify that the 35 ns switching speed meets the system timing requirements compared to faster alternatives in the family.
Part Context
This device belongs to the TS5A3159 series of low-voltage analog switches. It shares functional similarities with variants like the TS5A3159ADBVR, which offers a lower typical on-resistance of 900 mOhms. The standard TS5A3159DBVR provides a robust 1.1 Ohm specification suitable for general-purpose signal switching in portable devices.
Replacement Considerations
The TS5A3159DBVRE4 is a verified equivalent variant within the same product line. Designers may also consider the TS5A3159ADBVR for improved on-resistance performance if the application permits. Always verify pinout compatibility and thermal characteristics before substituting.
