Overview
The TMUX6122DGSR is a dual-channel analog switch IC manufactured by Texas Instruments, housed in an MSOP-10 surface-mount package. It features two single-pole single-throw (SPST) channels with a maximum on-resistance of 245 ohms. The device operates within a supply voltage range of 10 V to 16.5 V for single supplies or ±5 V to ±16.5 V for dual supplies. Key electrical parameters include a maximum propagation delay of 121 ns and a maximum off-time of 85 ns. It supports operation across a temperature range from -40°C to +125°C.
Feature Summary
- Dual-channel SPST configuration for independent signal routing
- Low power consumption suitable for battery-operated systems
- High isolation performance to minimize signal leakage
Applications
- Portable instrumentation signal conditioning
- Data acquisition systems multiplexing
- Industrial process control signal switching
Procurement Notes
Verify the specific ordering suffix DGSR corresponds to the reel packaging format required for automated assembly processes. Confirm that the MSOP-10 footprint matches the design layout specifications. Ensure compliance with RoHS directives and check moisture sensitivity levels for storage and reflow soldering requirements before procurement.
Selection Notes
Select this component when a dual-channel analog switch with moderate on-resistance is required. Compare against the TMUX6121 and TMUX6123 variants which share similar pinouts but may differ in channel count or specific electrical characteristics. Ensure the operating voltage range aligns with the system's power supply rails and that the thermal performance meets the application's ambient temperature constraints.
Part Context
This part belongs to the TMUX612x family of low-power analog switches from Texas Instruments. These devices are designed for applications requiring multiple independent signal paths in a compact form factor. The DGSR suffix indicates a tape-and-reel packaging option, facilitating high-volume manufacturing integration compared to tube-packaged alternatives.
Replacement Considerations
The TMUX6121DGSR and TMUX6123DGSR are direct pin-compatible replacements within the same series. Verify if the specific channel count or minor parameter variations between these variants meet the circuit requirements without necessitating schematic changes.
