Overview
The TMUX1204DGSR is a Texas Instruments analog multiplexer switch IC featuring a single 1 x 4:1 channel configuration housed in an MSOP-10 package. It operates on a single supply voltage ranging from 1.08 V to 5.5 V, with a maximum switch voltage of 5.5 V. Key electrical parameters include a maximum on-resistance of 9 Ohms and a maximum power supply current of 2 uA. The device supports fast switching with a maximum turn-on time of 20 ns and a maximum turn-off time of 20 ns. It functions reliably within an extended temperature range from -40°C to +125°C.
Feature Summary
- Ultra-low power consumption suitable for battery-operated systems
- High-speed signal switching with nanosecond transition times
- Low on-resistance for minimal signal attenuation
- Extended industrial temperature operation capability
Applications
- Multiplexing multiple analog signals to a single ADC input
- Signal routing in data acquisition systems
- General-purpose analog signal switching in portable devices
Procurement Notes
Verify the specific ordering suffix 'DGSR' corresponds to the MSOP-10 package and reel packaging format as documented by Texas Instruments. Confirm RoHS compliance status through official manufacturer datasheets or certified distributor documentation before finalizing procurement specifications.
Selection Notes
Select this component when a low-power, high-speed 1-to-4 analog switch is required within a 1.08 V to 5.5 V supply range. Ensure the application demands an on-resistance below 9 Ohms and switching speeds under 20 ns. Verify that the MSOP-10 footprint aligns with the PCB layout constraints and thermal requirements for the intended operating environment.
Part Context
This part belongs to the TMUX1204 series of general-purpose analog switches from Texas Instruments. It is distinct from other series like the TMUX1104, which offers lower leakage but different resistance characteristics. The DGSR suffix specifically denotes the surface-mount MSOP-10 package variant designed for automated assembly processes.
Replacement Considerations
The TMUX1104DGSR is a verified alternative within the same family offering lower on-state leakage current. Both parts share identical pinouts and packaging, facilitating direct substitution if leakage performance becomes the primary design constraint.
