Overview
The TMUX1072DGSR is a dual-channel analog switch IC from Texas Instruments, housed in a 10-VSSOP package. It operates on a single supply voltage ranging from 2.3 V to 5.5 V. The device features two SPDT (Single Pole Double Throw) switches with a maximum on-resistance of 18 Ohms and a channel-to-channel matching of 70 mOhm. Key switching parameters include a maximum turn-on time of 250 µs and a maximum turn-off time of 10 µs. It supports an operating temperature range from -40°C to +125°C and draws a maximum supply current of 110 µA.
Feature Summary
- Dual-channel SPDT configuration for signal routing
- Low on-resistance with tight channel-to-channel matching
- Latch-up immune design for enhanced reliability
- Wide operating temperature range suitable for industrial environments
Applications
- Data acquisition systems requiring signal multiplexing
- Industrial process control instrumentation
- Medical equipment signal conditioning
- Automotive sensor interfaces
Procurement Notes
Verify the specific ordering suffix DGSR corresponds to the 10-VSSOP package and reel quantity when sourcing. Confirm RoHS compliance status and manufacturing origin details against the latest datasheet revision. Ensure ESD handling precautions are followed during assembly due to the surface-mount nature of the component.
Selection Notes
Select this component when dual independent SPDT switching is required within a low-voltage single-supply system. The 18-ohm on-resistance is suitable for general-purpose analog signals but may require consideration for high-current applications. Compare turn-on/turn-off times against system timing requirements, as these are relatively slow compared to high-speed digital switches.
Part Context
This part belongs to the TMUX1072 family of precision analog switches. The DGSR suffix indicates the MSOP/VSSOP package type and tape-and-reel packaging format. It is distinct from other TMUX variants that may offer different channel counts, voltage ratings, or switching speeds.
Replacement Considerations
Direct pin-compatible substitutes within the same family include the TMUX1072DGS (tray packaging). Verify functional equivalence regarding on-resistance and voltage ratings when considering cross-family alternatives from other manufacturers.
