1. The IIO current sourced or sunk by the device must always respect the absolute maximum rating specified in Table 19:
Voltage characteristics, and the sum of the currents sourced or sunk by all the I/Os (I/O ports and control pins) must always
respect the absolute maximum ratings IIO.
2. TTL and CMOS outputs are compatible with JEDEC standards JESD36 and JESD52.
3. Guaranteed by design.
