Key Features
- ±60 V fault protection on all switch pins prevents damage from accidental overvoltage during hot-insertion or field wiring faults without external protection diodes
- 80 MHz signal bandwidth with low on-resistance supports routing of high-frequency analog signals up to audio and RF baseband frequencies
- 1.8 V logic-compatible control inputs allow direct interface with modern low-voltage microcontrollers and FPGAs without level-shifting circuits
- 8:1 channel configuration in a 16-pin SOP consolidates multi-channel analog routing into a single compact IC, reducing BOM complexity
Applications
TMUX7308FPWR is designed for automatic test equipment (ATE) and industrial data acquisition systems that must route analog signals from up to 8 field sensors to a single ADC while withstanding overvoltage events up to ±60 V. Its 80 MHz bandwidth enables accurate switching in audio measurement benches and instrumentation amplifier front ends where signal integrity across the multiplexed channels is critical. The 1.8 V logic compatibility and ±15 V analog supply range also suit PLC analog input modules and medical patient monitoring systems that require both low-voltage digital control and wide analog swing.

Frequently Asked Questions
How does TMUX7308FPWR protect circuits from overvoltage faults during field wiring events?
TMUX7308FPWR provides ±60 V fault protection on all switch pins, clamping transient overvoltage without requiring external series resistors or protection diodes. Even when the supply rails are unpowered, the protection circuitry remains active, preventing latch-up and pin damage during board power sequencing or accidental connection to 48 V industrial field wiring.
What signal frequencies can be reliably routed through TMUX7308FPWR in test and measurement applications?
TMUX7308FPWR is rated for 80 MHz nominal bandwidth, enabling accurate routing of audio-frequency, baseband RF, and wideband sensor signals without significant attenuation or phase distortion. In automatic test equipment, this allows a single TMUX7308FPWR to sequentially connect 8 DUT pins to a precision measurement instrument operating up to tens of megahertz.
Can TMUX7308FPWR be directly controlled by a 1.8 V microcontroller in a mixed-voltage system?
Yes, TMUX7308FPWR features 1.8 V logic-compatible control inputs, allowing direct connection to 1.8 V GPIO pins on modern ARM Cortex-M or FPGA I/O banks without level-shifting components. This simplifies the interface between a 3.3 V or 1.8 V digital control subsystem and the ±15 V analog signal path in data acquisition front ends.
Which supply voltage configuration does TMUX7308FPWR require and how does this affect analog input range?
TMUX7308FPWR operates from a negative supply of -5 V to -22 V and a positive supply, with a nominal operating point of ±15 V. This dual-supply configuration allows the analog input signals to swing across a wide range, typically matching the ±10 V full-scale range of industrial process sensors and standard test equipment ADC inputs, eliminating level-shifting requirements in the analog signal path.
