Overview
The TMUX6219RQXR is a single-channel, 2:1 (SPDT) CMOS analog switch manufactured by Texas Instruments. It operates with a supply voltage range of 4.5V to 36V (single), ±4.5V to ±18V (dual), or asymmetric configurations. The device supports bidirectional analog and digital signals from VSS to VDD on source and drain pins. Key electrical parameters include a typical on-resistance of 2.1Ω, a maximum continuous current of 440mA in the WSON package, and a bandwidth of 40MHz. It features 1.8V logic compatibility, fail-safe logic, and an operating temperature range of -40°C to +125°C.
Feature Summary
- Supports high current loads up to 440mA in the WSON package for demanding applications.
- Features fail-safe logic allowing control pin voltages to be applied before power supply rails.
- Provides rail-to-rail operation with bidirectional signal paths across the full supply range.
Applications
- Factory automation and industrial controls
- Programmable logic controllers (PLC)
- Semiconductor test equipment
- AC charging station infrastructure
- Ultrasound scanners
Procurement Notes
Verify the specific suffix RQXR corresponds to the WSON-8 package when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets automotive qualification requirements if deployed in vehicle systems, as indicated by the Q1 designation.
Selection Notes
Select this component for designs requiring high current handling and low on-resistance within a compact footprint. The WSON package offers superior thermal dissipation compared to VSSOP variants. Verify that the application logic levels are compatible with the 1.8V minimum input threshold for reliable switching operations.
Part Context
This part belongs to the TMUX621x family of precision switches and multiplexers from Texas Instruments. The family includes SPST variants like the TMUX6211, TMUX6212, and TMUX6213. The TMUX6219 specifically provides a 2:1 SPDT configuration suitable for signal routing tasks requiring break-before-make switching characteristics.
Replacement Considerations
TMUX6219DGKR is a direct functional equivalent available in a VSSOP-8 package. Both parts share identical electrical specifications but differ in physical dimensions and thermal performance characteristics due to the distinct packaging technologies.
