DC CHARACTERISTICS OF PINS BY I/O BUFFER TYPES

The following tables summarize the DC characteristics of all device pins described in Chapter 2 on page 39. The character-

istics describe the general I/O buffer types defined in Table 4 on page 41. For exceptions, see Section 7.2.9 on page 376.

For the DC characteristics of the analog pins, see Section 7.4 on page 378. The DC characteristics of the system interface

meet the PCI 2.1 3.3V DC signaling.
