Key Features
- ±60V fault protection and latch-up immunity safeguard both device and signal chain during overvoltage events in high-voltage industrial environments
- 150MHz -3dB bandwidth supports wideband analog signal routing for test instrumentation and data acquisition applications
- 1.8V logic-compatible control inputs enable direct interfacing to modern low-voltage microcontrollers and FPGAs without level-shifting circuitry
Applications
The TMUX7349FRTJR is designed for industrial test and measurement equipment where analog inputs may be subjected to fault voltages beyond the supply rails up to ±60V. Its dual 4:1 configuration and 150MHz bandwidth make it suitable for automated test equipment, signal conditioning front-ends, and medical diagnostic instruments. The 1.8V logic compatibility and fault threshold latch functionality simplify integration into modern mixed-signal systems that require both protection and high-frequency performance.

Frequently Asked Questions
How does the TMUX7349FRTJR protect circuits from overvoltage fault conditions?
The TMUX7349FRTJR tolerates fault voltages up to ±60V on its signal pins, clamping overvoltage events and asserting a fault flag without allowing latch-up. This 60V protection range exceeds typical ±15V supply operation, protecting downstream circuitry in industrial field-wiring environments where transients are common.
What bandwidth does TMUX7349FRTJR support for analog signal routing?
The device offers a 150MHz -3dB bandwidth, enabling accurate routing of high-frequency analog signals in test instrumentation and mixed-signal data acquisition systems operating well into the RF range, with on-resistance low enough to maintain signal integrity across the full 4:1 multiplexer configuration.
Can TMUX7349FRTJR be driven directly from a 1.8V FPGA or MCU GPIO?
Yes, the TMUX7349FRTJR accepts logic-high levels from 1.8V, making it directly compatible with 1.8V GPIO on modern FPGAs and low-power microcontrollers. No level-shifting components are needed between a 1.8V digital controller and the multiplexer select inputs, reducing BOM count and board area.
How does the dual 4:1 configuration of TMUX7349FRTJR benefit multi-channel measurement designs?
The dual 4:1 structure routes 8 single-ended inputs to 2 outputs in a single QFN-20 package, reducing channel-count ICs from 2 to 1 for stereo or differential measurement paths. This halves the multiplexer footprint and simplifies PCB routing in 8-channel data acquisition or sensor scanning applications.
