Overview
The TMUX7212RUMR is a four-channel analog switch IC from Texas Instruments, configured as four independent single-pole single-throw (SPST) switches. It operates within a supply voltage range of 4.5 V to 44 V for single-supply applications, or ±2.25 V to ±22 V for dual-supply configurations. The device features a maximum on-resistance of 2.5 Ohms, ensuring low signal attenuation. Switching performance includes a maximum turn-on time of 185 ns and a maximum turn-off time of 210 ns. It supports an extended industrial temperature range from -40°C to +125°C and is housed in a surface-mount package suitable for automated assembly.
Feature Summary
- Four independent SPST channels provide flexible signal routing capabilities
- High voltage operation up to 44 V accommodates diverse system requirements
- Low on-resistance minimizes insertion loss and power dissipation
- Latch-up immunity enhances reliability in harsh industrial environments
Applications
- Industrial process control signal multiplexing
- Data acquisition systems requiring high-voltage isolation
- Test and measurement equipment signal paths
- Medical instrumentation signal switching
Procurement Notes
Verify the specific ordering suffix to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure ESD handling procedures are followed during storage and installation. Cross-reference the datasheet revision date to validate parameter accuracy against current design requirements.
Selection Notes
Select this component when four independent low-resistance switches are required within a single package. The 44 V rating distinguishes it from lower-voltage alternatives like the TMUX6212. Verify that the 2.5 Ohm on-resistance meets the signal integrity needs of the application. Consider the WQFN-16 package dimensions for PCB layout constraints compared to other pin-count options.
Part Context
This part belongs to the TMUX7212 family of precision analog switches designed for robust industrial applications. It shares core electrical characteristics with variants such as the TMUX7212MPWR but differs in packaging and manufacturing lot specifications. The RUMR suffix typically denotes a specific reel-based packaging format intended for high-volume surface-mount production lines.
Replacement Considerations
The TMUX7212MPWR serves as a functional equivalent with identical electrical specifications but utilizes a TSSOP-16 package. Designers must adjust footprint layouts when substituting between WQFN and TSSOP packages. Other family members like the TMUX7236 offer different channel counts and configurations.
