Overview
The TMUX6221DGSR is a dual-channel, 1:1 single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It operates with a single supply voltage range of 4.5 V to 36 V or dual supplies from ±4.5 V to ±18 V. The device features a low on-resistance of 2.1 Ω and supports bidirectional signal transmission across the full supply range. It includes integrated pull-down resistors on logic pins and fail-safe logic for robust control. The component is housed in a 10-pin VSSOP package and functions within an operating temperature range of -40°C to +125°C.
Feature Summary
- Supports rail-to-rail bidirectional operation for both analog and digital signals
- Features fail-safe logic allowing control pin voltage application before power-up
- Includes integrated pull-down resistors on logic inputs to prevent floating states
Applications
- Wired networking equipment
- Remote radio units
- Patient monitoring and diagnostics systems
- Ultrasound scanners
- Optical test and networking equipment
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Ensure compatibility with required logic levels and thermal management constraints for the target PCB layout. Cross-reference the manufacturer's latest datasheet revision to confirm all electrical characteristics remain unchanged prior to final procurement decisions.
Selection Notes
Select this component when designing circuits requiring high-voltage analog switching with low on-resistance. Verify that the system logic levels are compatible with the 1.8 V input threshold. Consider the continuous current ratings relative to the ambient operating temperature to ensure the device remains within safe power dissipation limits during operation.
Part Context
This part belongs to the TMUX622x family of precision switches and multiplexers. It shares core architectural features with the TMUX6222, differing primarily in internal configuration or logic control requirements. Both devices utilize the same VSSOP-10 package and support identical supply voltage ranges and performance metrics defined in the shared family datasheet.
Replacement Considerations
The TMUX6222DGSR is a direct functional substitute within the same family. Verify that any alternative components meet the 36 V maximum supply rating and maintain comparable on-resistance values for signal integrity preservation in existing designs.
