1. The I
IO
current sourced or sunk by the device must always respect the absolute maximum rating specified in Table 21:
Voltage characteristics. 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 I
IO
.
2. Guaranteed by design.
3. TTL and CMOS outputs are compatible with JEDEC standards JESD36 and JESD52.
