Overview
The TS5A3159DBVT is a single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments, designed for low-distortion signal routing in portable applications. It operates on a single supply voltage ranging from 1.65 V to 5.5 V, ensuring compatibility with various logic levels. The device features a maximum on-resistance of 1.1 Ohms and supports bidirectional analog signals from 0 V to V+. Key electrical parameters include a maximum power supply current of 100 nA, a maximum switching time of 35 ns, and a maximum off-time of 20 ns. It functions within an operating temperature range of -40°C to +85°C and is housed in a SOT-23-6 surface-mount package.
Feature Summary
- Offers break-before-make switching action to prevent signal distortion during channel transitions.
- Provides high isolation in the powered-off state when the supply voltage is zero.
- Features 5.5 V tolerant control inputs for flexible interfacing with standard logic families.
Applications
- Portable audio equipment requiring low total harmonic distortion
- Battery-powered consumer electronics and sensing instruments
- Signal routing in mobile communication devices
Procurement Notes
Verify the specific suffix 'VT' against the official Texas Instruments datasheet to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a single SPDT switch with low on-resistance and high bandwidth is required. It is suitable for applications needing signal integrity preservation in low-voltage environments. Consider the SOT-23-6 package size for space-constrained designs. Verify that the 1.65 V minimum supply voltage aligns with the system's power architecture.
Part Context
The TS5A3159 belongs to the TS5A3159 family of analog switches from Texas Instruments. This series includes variants such as TS5A3159DBVR and TS5A3159ADBVR, which share similar functional characteristics but may differ in on-resistance tolerances or packaging options. The DBVT designation specifically indicates the SOT-23-6 package configuration with tape-and-reel delivery.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative SPDT analog switches from Texas Instruments or other manufacturers based on pin compatibility, on-resistance, and voltage specifications.
