Overview
The TS5A3159ADCKR is a single-channel, 2:1 analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 5.5V and features a maximum on-resistance of 900 milliohms. The device supports bidirectional signal transmission from 0V to V+ with low distortion characteristics. Key electrical parameters include a maximum charge injection of -20pC, an off-state leakage current of 20nA, and a channel capacitance of 18pF. Switching times are specified at a maximum of 30ns for turn-on and 20ns for turn-off. The component is housed in a SC-70-6 surface-mount package and functions across a temperature range of -40°C to +85°C.
Feature Summary
- Provides powered-off protection to isolate signals when the supply voltage is zero.
- Features break-before-make switching action to prevent signal distortion during channel transitions.
- Offers 5.5V tolerant control inputs for compatibility with various logic levels.
- Delivers low total harmonic distortion suitable for high-fidelity audio applications.
Applications
- Portable audio equipment requiring low distortion signal routing
- Battery-powered consumer electronics utilizing single-supply operation
- Signal multiplexing in sensing and instrumentation systems
Procurement Notes
Verify the specific suffix 'R' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as REACH compliant and free of antimony and bromine. Ensure the SC-70-6 package dimensions match the design constraints. Check for lead-free certification details corresponding to JESD-609 code e4 specifications.
Selection Notes
Select this component for designs requiring minimal on-resistance variation and low charge injection. The wide supply voltage range allows integration with both 1.8V and 5V logic systems. Consider the SC-70-6 footprint for space-constrained printed circuit board layouts. Evaluate the thermal performance within the specified industrial temperature range.
Part Context
This part belongs to the TS5A3159A series of analog switches. Variants such as TS5A3159ADCKRE4 and TS5A3159ADCKRG4 exist with identical functional specifications but differ in environmental compliance markings. The 'DCK' designation specifically identifies the SC-70-6 package type used in this model.
Replacement Considerations
TS5A3159ADCKRE4 and TS5A3159ADCKRG4 are confirmed equivalent parts within the same family. These variants maintain identical electrical and mechanical properties while adhering to specific environmental standards indicated by the suffixes.
