Hello,
I'm writing this message because I haven't found something very convenient, hope your advice will help !
I'm currently looking to an interface IC for a PLC application with Digital Input and Digital Output capabilities. In my dream, SPI interface is available with the possibility to configure the N ports of the IC as a Digital Input Type 1, 2 or 3 or as a Digital Output. Power supply is 24V. I do not need isolation (I can arrange this in the design at the SPI level).
I found a concurrent device at Maxim Integrated (MAX14906), and I'm looking for alternative to compare several references.
Thanks for the experience feedback !
Regards,
Joel
