Overview
The TMUX1119DBVR is a single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments, housed in a SOT-23-6 package. It operates on a supply voltage range of 1.08V to 5.5V with an operating temperature range of -40°C to +125°C. Key electrical parameters include a maximum on-resistance of 4.9Ω at 5V and 125°C, and a typical off-leakage current of 3pA. The device supports bidirectional signal paths from GND to VDD and features 1.8V logic compatible inputs.
Feature Summary
- Ultra-low leakage current for high precision measurement applications
- Fail-safe logic allows control pin voltages to be applied before the power supply
- Bidirectional signal path supporting both analog and digital signals
- Break-before-make switching prevents short circuits during channel transitions
Applications
- Ultrasound scanners
- Patient monitoring and diagnostics equipment
- Data acquisition systems
- Semiconductor test equipment
- Programmable logic controllers (PLC)
Procurement Notes
Verify the specific ordering suffix DBVR corresponds to the SOT-23-6 package and tape-and-reel quantity when sourcing. Confirm that the component meets RoHS compliance requirements for the intended manufacturing process. Ensure the supplier provides valid traceability documentation for production-grade parts.
Selection Notes
Select this component for applications requiring low charge injection and minimal signal distortion. The wide supply range accommodates various logic levels, while the small footprint suits space-constrained designs. Evaluate thermal performance if continuous current ratings approach limits at elevated temperatures.
Part Context
This part belongs to the TMUX1119 family of precision switches designed for low-power, high-accuracy signal routing. It shares core specifications with other variants like the DCK package version but differs in physical dimensions and thermal characteristics. The series targets portable and industrial instrumentation markets.
Replacement Considerations
The TMUX1119DCKR serves as a direct functional substitute using the SC70-6 package. Verify pin compatibility and thermal derating curves when swapping between SOT-23-6 and SC70-6 footprints.
