Maximum Junction Temperature of ADM3491 is not available in datasheet. Please provide the same
I would like to ask how to implement half duplex in ADM3491? By shorting A to Y and B to Z?
According to ADM3491-1 datasheet, this part " Meets IEC1000-4-4" as below,
What difference between IEC1000-4-4 and IEC610004-4?
IEC61000-4-4 covered IEC10004-4?
Thank you for your help in advance.
Can you please explain the connection of the ADM3491 bus pins to the MOXA UPort 1130?
Is the ADM3491 wired up to the MOXA UPort 1130 correctly? Can you check the pin-outs?
And for R33 - what is the resistance value?
The maximum Icc for the ADM3491 is about 70mA with 54 Ω loading at temperature 85C.
ADM3491-1 is not recommended for new design rather than obsolete, as you could find more information here:Product Life Cycle Information
I cannot give you the accurate lifetime of this product but it should last at least more than 2 years.
