Key Features
- Dual 4:1 channel configuration providing two independent multiplexed signal paths in one package
- 44 V latch-up immunity and ±22 V dual supply range for robust industrial signal handling
- 1.8 V logic-compatible control inputs enabling direct interfacing with low-voltage microcontrollers
- 31 MHz bandwidth supporting precision signal routing up to audio and low-RF frequencies
Applications
The TMUX7209RUMR is designed for industrial data acquisition systems, medical instrumentation, and automated test equipment where two independent 4-input signal buses must be multiplexed to separate ADC channels simultaneously. Its 44 V latch-up immunity and -40°C to 125°C rating make it reliable in harsh industrial environments with transient overvoltage events. The dual 4:1 topology also supports differential signal multiplexing, selecting one of four differential sensor pairs for precision measurement in bridge sensor and thermocouple acquisition cards.

Frequently Asked Questions
How does the dual 4:1 topology of TMUX7209RUMR differ from a single 8:1 multiplexer like TMUX7208?
The TMUX7209RUMR provides two independent 4:1 multiplexed paths that can be controlled simultaneously, whereas an 8:1 single-channel mux like the TMUX7208RUMR routes 8 inputs to one common output. This makes the TMUX7209RUMR ideal for differential signal multiplexing — one 4:1 mux selects the positive input while the second selects the negative, maintaining signal balance across all 4 differential input pairs.
What does 44 V latch-up immunity mean for TMUX7209RUMR, and why does it matter in industrial designs?
The 44 V latch-up immunity means the TMUX7209RUMR can withstand transient overvoltage events of up to 44 V on its signal pins without entering a destructive latch-up condition, even when VCC is 0 V. In industrial field wiring environments where inductive load switching and cable capacitance can generate spikes well above the 22 V supply rail, this protection prevents device failure and protects downstream ADCs from overvoltage damage.
What is the signal bandwidth of TMUX7209RUMR, and which applications fit within its frequency response?
The TMUX7209RUMR has a nominal bandwidth of 31 MHz, making it appropriate for audio signal routing (20 Hz to 20 kHz), low-frequency sensor acquisition, and moderate analog signal frequencies up to 31 MHz. For higher-frequency applications above 50 MHz such as IF signal routing, a wider-bandwidth switch in Texas Instruments' TMUX family would be needed.
For a multi-channel thermocouple data logger, how many TMUX7209RUMR ICs are needed to scan 8 differential thermocouple inputs?
Each TMUX7209RUMR handles 4 differential input pairs using its dual 4:1 topology. To scan 8 differential thermocouple inputs, 2 TMUX7209RUMR devices are required — one handles channels 1–4 and the other handles channels 5–8, with address pins and enable logic controlled by a microcontroller. This approach reduces component count compared to using 4 single-ended 8:1 muxes for the same task.
