Overview
The TS5A23157QDGSRQ1 is an automotive-grade 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 and features a maximum on-resistance of 10 Ohms. The device supports a continuous DC switch current of 100 mA with a maximum power supply current of 750 nA. Key timing specifications include a maximum turn-on time of 57 ns and a maximum turn-off time of 3.8 ns. It is housed in a 10-pin MSOP package and is qualified under the AEC-Q100 standard for operation within a temperature range of -40°C to +125°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
- Dual SPDT configuration enabling independent control of two signal paths.
- Low on-resistance design supporting high-speed signal switching applications.
Applications
- Automotive infotainment system signal routing
- CAN bus channel switching and isolation
- Audio/video signal path selection in automotive displays
Procurement Notes
Verify the specific suffix Q1 indicates automotive catalog qualification and extended temperature range capabilities. Confirm the DGSR package designation matches the required MSOP-10 footprint for PCB layout compatibility. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability and authenticity before procurement.
Selection Notes
Select this component when automotive reliability and wide operating temperature ranges are required. Compare the 10 Ohm on-resistance against application signal integrity needs. Verify that the 1.65 V minimum supply voltage aligns with the system power rails. Consider the 100 mA switch current limit for load driving capabilities. Evaluate the 57 ns switching speed against the required signal bandwidth and timing constraints.
Part Context
This part belongs to the TS5A23157 family of dual SPDT analog switches. The Q1 suffix denotes automotive catalog grade, distinguishing it from commercial variants like the TS5A23157DGSRG4 which typically have lower temperature limits. The family shares similar electrical characteristics but differs in qualification standards and operational temperature ranges defined by the manufacturer.
Replacement Considerations
TS5A23157DGSRG4 offers identical electrical performance but lacks automotive qualification and has a limited temperature range of -40°C to +85°C. TS5A623157DGSR provides similar functionality with potentially different switching speeds but requires verification of automotive suitability. Direct pin-to-pin replacements must match the MSOP-10 package and AEC-Q100 requirements if used in automotive contexts.
