Part Number: TMUX7462F
Hello,
I integrated the TMUX7462F as protection from voltages above 4V according to the following draft into my system:
According to the datasheet, my expectation was that the switch SW should open, once Vsource exceeds 4V (3…
Part Number: TMUX7462F
Hello,
I use the TMUX7462F for protecting my measurement electronics from above 4V and used the following setup for testing:
When VFP is left floating, D1 can be measured with GND potential. However, if I now connect 3.3 V to…
Part Number: TMUX7462F Other Parts Discussed in Thread: TMUX741-746EVM Hi,
About the "Supplying the VFP pin with a series diode" topic, the answer includes "VFN at 0.5V then the clamping voltage should be around -0.2V".
I have just noticed…
Part Number: TMUX7462F We need to protect a 3-wire RTD measurement circuit to 48V short circuit on any input.
Would one TMUX7462F powered at 10V accomplish this task?
We need to clamp the inputs to maximum 3.3V, so can we assume we need to connect Vfp…
Part Number: TMUX7462F
Hi,
TMUX7462F protects from overvoltage beyond the VFP+VT I need to protect a 5V level signal with GND-0.3V to 5V+0.3V (absolute max) range. If I connect VPF pin to 5V supply, max voltage on the signal can go up to 5.7V before cut…
Part Number: TMUX7462F Hello Guys,
Good day.
Our customer is looking at the TMUX7462F as an alternative to a part they are using in a current design. They are trying to understand how the device would perform if both the DR and FF pins were left completely…
Part Number: TMUX7462F 1. Considering that the typical impedance of a CAN bus is 120Ω, is the maximum on-resistance of 16Ω an issue? My customer designs the system considering the minimum impedance of CAN can reach 60Ω and manifested concern in using…
Hey Matthew, Thanks for reaching out and excited to hear about your project and hope all goes well! So to answer your questions, typically you can find the footprint in the CAD/CAE symbols library on the product page and going to this link: However, I'm seeing…
The absolute maximum ratings forbid voltages above V DD + 0.5 V; there are clamping diodes from the I/O pins to V DD .
You can create a separate power rail, but the muxes would still be powered up. And you must limit the clamp current to less than 30 mA…
IO-Link transceivers like the TIOL111 implement one high-voltage I/O, but do not support TTL levels on the external interface.
There are switches that protect against up to ±60 V (more requires a TVS). TMUX7462F is a plain protection device; TMUX7412F…
