Overview
The TS5A23159RSER is a dual 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. The device features a maximum on-resistance of 1.1 Ohms and a channel-to-channel matching of 50 mOhms. Switching times are specified with a maximum turn-on time of 13 ns and a maximum turn-off time of 8 ns. The component supports a maximum switch current of 100 mA and offers a 3 dB bandwidth of 100 MHz. It is housed in a 10-UQFN package measuring 2.0x1.5 mm and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual SPDT configuration for signal routing applications
- Low on-resistance for minimal signal attenuation
- High-speed switching capabilities suitable for data acquisition
- Compact surface-mount packaging for space-constrained designs
Applications
- Portable instrumentation signal conditioning
- Audio and video signal path switching
- Data acquisition systems multiplexing
- Communication equipment signal routing
Procurement Notes
Verify the specific ordering suffix RSER corresponds to the required tape and reel quantity of 3000 units. Confirm that the UQFN-10 package dimensions align with the PCB footprint requirements. Ensure the single-supply voltage range meets the system power constraints. Check RoHS compliance status against environmental regulations applicable to the final assembly location.
Selection Notes
Select this component when low on-resistance and high bandwidth are critical for signal integrity. Compare against the TS3A24157 if lower on-resistance is needed but voltage range is limited. Consider the TS5A23157 if higher on-resistance is acceptable for cost reduction. Verify that the 100 mA switch current rating exceeds the maximum load current in the application circuit.
Part Context
This part belongs to the TS5A23159 family of analog switches from Texas Instruments. It shares functional similarities with other devices in the series but differs in specific electrical parameters such as on-resistance and speed. The RSER suffix indicates the reel packaging format used for automated assembly processes.
Replacement Considerations
The TS5A23159R is a compatible alternative with identical electrical specifications. Verify pinout compatibility before substitution. The TS3A24157 offers lower on-resistance but has a reduced maximum supply voltage. Ensure any replacement maintains the same package type or includes necessary adapter considerations.
