Electrical characteristics
Output voltage levels
Unless otherwise specified, the parameters given in Table 47 are derived from tests
performed under ambient temperature and V_DD supply voltage conditions summarized in
Table 10. All I/Os are CMOS and TTL compliant.

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. TTL and CMOS outputs are compatible with JEDEC standards JESD36 and JESD52.
3. 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.
4. Based on characterization data, not tested in production.
