Electrical Characteristics
All voltages are reference to ground. Currents flowing into the circuit have positive values.
The absolute maximum ratings of the SCA3000 are presented in Table 15 below.

Please refer to the corresponding product datasheet.
Table 16. DC characteristics of digital I/O pins.
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.
