Electrical characteristics

123

Note:

It is recommended to add a Schottky diode (pin to ground) to analog pins which may

potentially inject negative currents.

I/O port characteristics

General input/output characteristics

Unless otherwise specified, the parameters given in Table 53 are derived from tests

performed under the conditions summarized in Table 14. All I/Os are CMOS and TTL

compliant.
