Overview
The TS5A3159DCKRE4 is a single-channel, 2:1 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 power supply current of 100 nA, a maximum propagation delay (Ton) of 35 ns, and a maximum turn-off time (Toff) of 20 ns. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a compact SC-70-6 surface-mount package.
Feature Summary
- Provides break-before-make switching action to prevent signal distortion during channel transitions.
- Offers powered-off protection to isolate signals when the device is unpowered.
- Features control inputs tolerant up to 5.5 V for compatibility with various logic levels.
Applications
- Portable audio equipment requiring low distortion signal routing
- Battery-powered consumer electronics and portable devices
- Signal multiplexing and demultiplexing in sensing and instrumentation systems
Procurement Notes
Verify the specific suffix E4 indicates lead-free compliance and RoHS standards before procurement. Confirm the SC-70-6 package dimensions match the target PCB footprint. Ensure the 1.1 Ohm on-resistance meets the application's signal integrity requirements compared to lower resistance alternatives like the ADCKR variant.
Selection Notes
Select this component when a balance between low on-resistance and robust powered-off protection is required. The 1.1 Ohm Ron is slightly higher than the 900 mOhm variant but offers verified performance in standard SPDT applications. Consider the 35 ns switching speed adequate for general-purpose analog signal routing rather than high-frequency RF paths.
Part Context
This part belongs to the TS5A3159 family of single-pole double-throw analog switches. It shares functional similarities with the TS5A3159ADBVR and TS5A3159ADCKT but differs in package type and specific electrical tolerances. The E4 suffix denotes environmental compliance modifications within the same product line.
Replacement Considerations
The TS5A3159ADCKR serves as a direct pin-compatible alternative with a lower 900 mOhm on-resistance. The TS5A3159DCKT is another related variant in the same series. Verify that the replacement's switching speed and leakage current specifications align with the original design constraints.
