Overview
The TS5A3159AYZTR is a single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments, housed in a 6-pin DSBGA package. It operates on a single supply voltage ranging from 1.65 V to 5.5 V. The device features a maximum ON-state resistance of 1.1 Ω at 5 V and 2 Ω at 3.3 V, with excellent ON-state resistance matching. Key electrical parameters include a bandwidth of 100 MHz, off-isolation of -64 dB at 1 MHz, and low charge injection. It supports an operating temperature range from -40°C to +85°C and includes break-before-make switching to prevent signal distortion.
Feature Summary
- Specified break-before-make switching prevents signal distortion during channel transitions.
- Provides high isolation in power-down mode when the supply voltage is zero.
- Features low ON-state resistance and excellent matching for minimal signal attenuation.
- Control inputs are tolerant up to 5.5 V, allowing compatibility with various logic levels.
Applications
- Cell phones
- Portable instrumentation
- Audio and video signal routing
- Low-voltage data acquisition systems
Procurement Notes
Verify the specific YZP package designation and tape-and-reel configuration against the manufacturer's orderable addendum. Confirm that the component meets RoHS compliance standards and matches the exact revision level required for the design. Ensure ESD handling protocols are followed due to the sensitivity of the CMOS input structure.
Selection Notes
Select this component for applications requiring a compact footprint and low ON-resistance in portable devices. The 1.65 V minimum supply voltage makes it suitable for battery-operated systems. Consider the thermal resistance characteristics of the DSBGA package when designing for high ambient temperatures or limited airflow conditions.
Part Context
This part belongs to the TS5A3159 family of analog switches. It is terminal compatible with the TS5A3159 device, facilitating direct pin-to-pin upgrades or replacements in existing designs. The family offers variations in packaging, including SOT-23 and SC-70, to suit different board space constraints.
Replacement Considerations
The datasheet explicitly states terminal compatibility with the TS5A3159 device. Designers should verify that any substitute maintains the same DSBGA footprint and electrical specifications to ensure seamless integration without PCB layout modifications.
