Overview
The TS5A3159DCKT 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 analog signal transmission from 0 V to V+ with low distortion. 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 SC70-6 surface-mount package.
Feature Summary
- Break-before-make switching action prevents signal distortion during channel transitions
- Low charge injection and on-resistance matching ensure minimal signal degradation
- Control inputs tolerate up to 5.5 V for compatibility with various logic levels
- Provides high isolation in power-down mode when the supply voltage is zero
Applications
- Portable audio equipment requiring low total harmonic distortion
- Battery-powered consumer electronics and portable instruments
- Signal routing in communication and networking devices
- Multiplexing and demultiplexing in sensing and measurement systems
Procurement Notes
Verify the specific suffix DCKT against the manufacturer's official datasheet to confirm the SC70-6 package type and tape-and-reel orientation. Confirm RoHS compliance status and lead-free material declarations directly from the latest production documentation. Ensure the component matches the intended thermal and mechanical specifications for the target assembly process.
Selection Notes
Select this component when a single SPDT switch is required for signals between 0 V and the positive supply rail. It is suitable for applications demanding low on-resistance and high linearity. Consider alternative packages if space constraints differ from the SC70-6 footprint. Verify that the 5.5 V control input tolerance aligns with the system's logic voltage levels.
Part Context
This part belongs to the TS5A3159 family of low-voltage analog switches designed for portable applications. It shares functional similarities with other members like the TS5A3159ADBVR but differs in packaging and specific electrical tolerances. The series is optimized for battery-operated devices where low power consumption and signal integrity are critical design factors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameter equivalence before considering any cross-reference components from other manufacturers or different TI series.
