1. The IIO current sourced or sunk by the device must always respect the absolute maximum rating specified in Table 21:

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 ΣIIO.

2. TTL and CMOS outputs are compatible with JEDEC standards JESD36 and JESD52.

3. Guaranteed by design.
