Frequently Asked Questions
What supply voltage range does TMUX7208RUMR support, and how does this benefit industrial sensor interfacing?
The TMUX7208RUMR operates from dual supplies ranging from ±4.5 V up to ±22 V, allowing it to directly handle ±10 V industrial signal ranges common in 4–20 mA loop transmitters and ±15 V op-amp output rails. This eliminates the need for signal attenuators or level-shift circuits in many data acquisition front-ends, reducing component count.
What is the signal bandwidth of TMUX7208RUMR, and for which signal frequencies is it appropriate?
The TMUX7208RUMR has a nominal bandwidth of 30 MHz, making it suitable for audio signals, sensor outputs up to tens of kilohertz, and moderate-frequency test signals up to 30 MHz. For RF multiplexing above 100 MHz, higher-bandwidth switches such as the TMUX7308 series would be more appropriate.
How is the TMUX7208RUMR selected among 8 inputs, and what interface does the control logic use?
Channel selection on the TMUX7208RUMR is controlled by 3 digital address pins (A0, A1, A2) and an enable pin, supporting binary-coded selection of any 1 of 8 inputs. The control logic is compatible with 1.8 V to 5.5 V digital levels, making it directly interfaceable with microcontrollers and FPGAs operating at 3.3 V or 5 V logic.
For a 16-channel data acquisition system, how can two TMUX7208RUMR ICs be combined to expand input count?
Two TMUX7208RUMR devices can be cascaded by connecting their common outputs through a second-stage 2:1 mux or by using a separate address decoder to assert each IC's enable line selectively. This doubles the effective input count to 16 channels while requiring only 4 address bits (3 channel bits + 1 chip-select bit), a common approach in multi-channel industrial DAQ boards.
