Overview
The TS5A23166DCURE4 is a dual single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It operates from a single supply voltage ranging from 1.65 V to 5.5 V. The device features a low on-state resistance of 0.9 ohms and excellent channel-to-channel matching of 40 milliohms. Key electrical parameters include a maximum power supply current of 100 nA, a maximum switch DC current of 100 mA, and a maximum leakage current of 20 nA. Switching times are specified with a maximum turn-on time of 7.5 ns and a maximum turn-off time of 11 ns. The component is housed in an 8-VSSOP package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides high isolation in powered-down mode when the supply voltage is zero.
- Features control inputs that are tolerant up to 5.5 volts for flexible interfacing.
- Delivers low total harmonic distortion suitable for precision signal routing.
- Exhibits latch-up performance exceeding 100 mA per JESD 78 Class II standards.
Applications
- Portable audio applications requiring low distortion
- Cell phones and wireless terminals
- Portable instrumentation and data-acquisition systems
- Audio and video signal routing circuits
Procurement Notes
Verify the suffix E4 indicates lead-free compliance and RoHS status against the manufacturer's current documentation. Confirm the package type matches the required footprint for PCB layout. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the datasheet revision date to confirm parameter validity.
Selection Notes
Select this component for designs requiring low on-resistance and precise channel matching in dual SPST configurations. The 5.5-volt tolerant control inputs allow direct interface with standard logic levels without level shifting. Consider the 8-VSSOP package size for space-constrained portable electronics. Verify that the 100 mA switch current capability aligns with the load requirements of the application.
Part Context
This part belongs to the TS5A23166 series of dual SPST analog switches. The E4 suffix typically denotes lead-free packaging compliant with RoHS directives. It serves as a low-power alternative to higher-current switches in portable devices. The device is designed to minimize signal distortion in audio and video paths.
Replacement Considerations
TS5A23166DCUR is a functionally equivalent variant within the same series. TS5A23166DCURG4 is another verified lead-free option with identical electrical characteristics. Verify pinout compatibility before substitution.
