Overview
The TS5A23166YZPR 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 Ω and excellent channel-to-channel matching. Key electrical parameters include a maximum on-resistance of 1.1 Ω, a maximum operating frequency of 150 MHz, and a maximum power supply current of 100 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 supports an input/output voltage range up to the supply rail and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Offers high isolation in powered-down mode when the positive supply is zero.
- Features control inputs that are tolerant to 5.5 V signals.
- Provides low charge injection for accurate signal switching.
- Delivers excellent total harmonic distortion performance suitable for audio applications.
Applications
- Cell phones
- Portable instrumentation
- Audio and video signal routing
- Low-voltage data-acquisition systems
Procurement Notes
Verify the package type matches the design requirements, as this specific suffix indicates a DSBGA-8 package. Confirm the order quantity aligns with distributor cut tape or reel policies. Ensure the voltage ratings of the application circuit remain within the 1.65 V to 5.5 V operational limits. Check for RoHS compliance documentation if required by the manufacturing process. Validate the lead time estimates provided by suppliers against project schedules.
Selection Notes
Select this component when a dual SPST configuration is required for low-voltage signal routing. The low on-resistance makes it suitable for maintaining signal integrity in sensitive paths. Consider the UFBGA/DSBGA footprint constraints during PCB layout. Compare switching speeds and leakage currents against alternative switches if high-frequency performance is critical. Ensure the control logic levels are compatible with the 5.5 V tolerant inputs.
Part Context
This part belongs to the TS5A23166 family of analog switches. Other variants in the series include different packaging options such as VSSOP-8 (TS5A23166DCUR) and standard UFBGA-8 (TS5A23166YZTR). All variants share identical electrical characteristics but differ in physical dimensions and mounting styles. The family is designed for portable electronics requiring small footprints and low power consumption.
Replacement Considerations
Direct pin-compatible substitutes include TS5A23166DCUR and TS5A23166YZTR. Verify that the replacement package fits the existing PCB footprint. Electrical parameters such as on-resistance and bandwidth should be comparable. Ensure the thermal performance of the alternative package meets the application's dissipation requirements.
