Is it required to put external TVS diodes along with the ST4485EB RS485 IC on the A and B lines? I see the datasheet and notice that there is in-built ESD protection as shown in the data sheet snapshot below. Please advise.  

Hi,The ST4485EB IC mentions that it needs a 3v3 supply. How can we ensure that the A and B lines interoperate with other RS485 devices working at a 5V logic level as the datasheet mentions . Should I just provide 5V supply to this chip so that it int...

Hi All,I wanted to move from STM32F401 to a ECC enabled MCU and came across the STM32U575/585 series. Is it possible to in place use the QFN48 package for stm32u575 in place of stm32f401?. The pinouts/ports/power pins all look to be the same. are the...
