Overview
The TS5A3159ADCKT is a single-channel, 2:1 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 mOhms. The device supports bidirectional I/O signals from 0 V to V+ with low distortion characteristics. Key electrical parameters include a maximum power supply current of 500 nA, a maximum switch DC of 100 mA, and a -3 dB bandwidth of 100 MHz. Switching times are specified at a maximum of 30 ns for turn-on and 20 ns for turn-off. The component is housed in a SC-70-6 surface-mount package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Powered-off protection ensures isolation when the supply voltage is zero.
- Break-before-make switching action prevents signal distortion during channel transitions.
- Low charge injection and high on-resistance matching minimize signal integrity loss.
Applications
- Portable audio equipment requiring low distortion
- Battery-powered consumer electronics
- Signal routing in sensing and instrumentation systems
Procurement Notes
Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead time requirements directly with authorized distributors or the manufacturer. Ensure the component meets environmental regulations applicable to the target market before finalizing procurement orders.
Selection Notes
Select this component for applications requiring a compact SPDT switch with powered-off protection. Compare on-resistance and leakage current specifications against alternative models if strict signal fidelity is required. Verify that the control logic voltage levels are compatible with the 1.65 V to 5.5 V operating range.
Part Context
This part belongs to the TS5A3159A series of analog switches. It shares functional similarities with variants such as TS5A3159DCKR and TS5A3159ADBVR, differing primarily in packaging and minor electrical tolerances. The series is designed for general-purpose signal switching in space-constrained portable devices.
Replacement Considerations
TS5A3159ADCKTG4 and TS5A3159ADCKTE4 are confirmed equivalent parts within the same family. These variants maintain identical electrical performance and pinout configurations while potentially differing in manufacturing lot details or specific environmental certifications.
