1. The I
IO
current sunk by the device must always respect the absolute maximum rating specified in Table 8
and the sum of I
IO
(I/O ports and control pins) must not exceed I
VSS
.
2. The I
IO
current sourced by the device must always respect the absolute maximum rating specified in
Table 8 and the sum of I
IO
(I/O ports and control pins) must not exceed I
VDD
.
3. TTL and CMOS outputs are compatible with JEDEC standards JESD36 and JESD52.
4. Based on characterization data, not tested in production.
