Overview
The TMUX1109RSVR is a dual 4:1 multiplexer switch IC manufactured by Texas Instruments, housed in a 16-UQFN package. It operates on a single supply voltage ranging from 1.08 V to 5.5 V or dual supplies up to ±2.75 V. Key electrical parameters include a maximum on-state resistance of 4.9 ohms and a channel-to-channel matching of 180 milliohms. The device features a -3dB bandwidth of 135 MHz, with maximum turn-on and turn-off times of 20 ns and 9 ns respectively. Supply current is limited to 1 uA maximum, while off-state leakage current reaches 80 pA. It supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Offers low on-state resistance for minimal signal attenuation
- Provides high bandwidth performance suitable for signal integrity
- Features ultra-low power consumption for energy-efficient designs
Applications
- Data acquisition systems requiring signal routing
- Industrial process control instrumentation
- Medical equipment signal conditioning
Procurement Notes
Verify the specific suffix RSVR confirms the UQFN-16 package and reel packaging configuration. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and traceability before procurement.
Selection Notes
Select this component when dual independent 4-to-1 multiplexing is required within a compact footprint. Compare against the TMUX1209 if higher on-resistance is acceptable for simplified control logic. Consider the TMUX1108 if a single 8:1 configuration better suits the circuit topology instead of two separate channels.
Part Context
This part belongs to the TMUX1109 series of analog switches designed for general-purpose applications. It shares the same UQFN-16 form factor as other devices in the family, such as the TMUX1108 and TMUX1112, facilitating board layout standardization across different multiplexing configurations within Texas Instruments' portfolio.
Replacement Considerations
The TMUX1109RSWR serves as a pin-compatible alternative in a smaller WSON package. For direct replacement in existing layouts, verify that the thermal characteristics of the alternative package meet the system's dissipation requirements without modifying the PCB copper area.
