Digital I/O level shifter

All the SCA3000 products have an internal level shifter that can be used to interface e.g. a micro

controller using lower supply than the SCA3000. The level shifter is "programmed" by providing the

supply voltage of the interfaced device to the DVIO-pin. Please refer to the corresponding product

data sheet for details.
