Overview
The TS5A3159DBVRE4 is a single-channel, single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and is housed in a six-pin SOT-23 package. The device features a maximum on-resistance of 1.1 ohms and supports bidirectional signal transmission. Key electrical specifications include a maximum turn-on time of 35 ns and a maximum turn-off time of 20 ns. It functions within an ambient temperature range of -40°C to +85°C.
Feature Summary
- Provides powered-off protection to isolate signals when the supply voltage is removed.
- Supports bidirectional analog signal transmission across the full supply voltage range.
- Features low charge injection to minimize signal distortion during switching.
Applications
- Portable audio equipment requiring low distortion
- Battery-powered consumer electronics
- Signal routing in mobile communication devices
Procurement Notes
Verify the E4 suffix indicates lead-free compliance and RoHS adherence per Texas Instruments documentation. Confirm the SOT-23-6 package dimensions match design constraints. Ensure the operating temperature range meets system requirements. Check for obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component for applications requiring a single SPDT switch with low on-resistance and wide voltage compatibility. Compare against the TS5A3159ADBVR if lower on-resistance is required. Verify that the 1.1-ohm resistance and 100-nA supply current align with power budget constraints. Ensure the logic input levels are compatible with the system control voltages.
Part Context
This part belongs to the TS5A3159 family of analog switches designed for portable applications. The DBVR suffix denotes the SOT-23-6 tape and reel packaging format. The E4 suffix specifically identifies the lead-free and RoHS-compliant version of the device, distinguishing it from standard commercial variants.
Replacement Considerations
The TS5A3159DBVT serves as a pin-compatible alternative in different packaging. The TS5A3159DCKT offers the same functionality in an SC-70-6 package. Cross-reference datasheets to verify parameter alignment before substitution.
