Overview
The TS5A3357QDCURQ1 is a single-channel SP3T analog switch designed for automotive applications, certified under AEC-Q100 standards. It operates on a single supply voltage ranging from 1.65V to 5.5V within an extended temperature range of -40°C to 125°C. Key electrical specifications include a maximum on-state resistance of 15 ohms and a channel-to-channel matching of 100 milliohms. The device features a -3dB bandwidth of 334MHz, with maximum switching times of 10ns for turn-on and 6.5ns for turn-off. Additional parameters include a charge injection of 3.4pC, off-state leakage current up to 200nA, and crosstalk of -62dB at 10MHz.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q100 qualification standards
- Single-pole triple-throw (SP3T) configuration for signal routing flexibility
- Low on-state resistance ensuring minimal signal loss in active paths
- High bandwidth capability supporting high-frequency signal integrity
Applications
- Automotive infotainment system signal switching
- Vehicle sensor data multiplexing and demultiplexing
- In-cabin connectivity interface management
Procurement Notes
Verify the presence of the Q1 suffix to confirm automotive grade status and AEC-Q100 certification. Ensure the DCUR package variant matches the required PCB footprint. Confirm the operating temperature range meets the specific environmental demands of the target application before finalizing component selection.
Selection Notes
Select this component when automotive qualification is mandatory for the design. Compare the 15-ohm on-resistance against system requirements to ensure acceptable voltage drop. Evaluate the 334MHz bandwidth to verify suitability for the highest frequency signals in the application. Consider the 8-VSSOP package dimensions for layout constraints.
Part Context
This part belongs to the Texas Instruments TS5A3357 family of low-voltage analog switches. The Q1 designation specifically indicates it is engineered for automotive environments, distinguishing it from standard commercial variants like the TS5A3357DCUR by its extended temperature rating and reliability testing protocols.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative SP3T switches based on pinout and electrical parameter alignment if sourcing changes occur.
