Overview
The TMUX1104DGSR is a single-channel, 4:1 precision analog multiplexer manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.08 V to 5.5 V. Key electrical specifications include a maximum on-state resistance of 4.9 Ohms and a maximum power supply current of 8 nA. The device features a maximum on-time of 18 ns and an off-time of 9 ns. It supports an input voltage range up to 5.5 V and functions within a temperature range of -40°C to +125°C. The component is housed in a 10-lead MSOP package.
Feature Summary
- Ultra-low leakage current performance suitable for high-impedance signal paths
- Precision switching with low on-state resistance for minimal signal attenuation
- Wide single-supply operating voltage range compatible with various logic levels
Applications
- Data acquisition systems requiring precise signal routing
- Medical instrumentation with strict leakage current constraints
- Industrial process control signal conditioning
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when low leakage current is critical compared to general-purpose switches like the TMUX1204. The TMUX1104DGSR offers superior leakage performance at the cost of slightly higher on-resistance than some alternatives. Evaluate the MSOP-10 package dimensions against available PCB real estate. Confirm that the 1.08 V minimum supply voltage aligns with the system's power architecture.
Part Context
This part belongs to the TMUX1104 series of precision multiplexers designed for low-leakage applications. It serves as a specialized alternative to standard analog switches where signal integrity and minimal current draw are paramount. The DGSR suffix indicates the specific MSOP-10 packaging and reel configuration used for surface-mount assembly processes.
Replacement Considerations
The TMUX1108PWR is a related Texas Instruments multiplexer offering 8:1 configuration in a TSSOP-16 package. Verify pinout compatibility and package footprint differences before substitution. Other family members may offer different channel counts or leakage characteristics.
