Note 5.6 This specification applies to all IS type inputs and tri-stated bi-directional non-PCI pins. Internal pull- down and pull-up resistors add +/- 50μA per-pin (typical)

Note 5.7 This buffer type adheres to Section 4.2.2 (3.3V Signaling Environment) of the PCI Local Bus Specification Revision 3.0. Device signals are NOT 5V tolerant. This device must not be used in a 5V PCI system, or connected to 5V logic without appropriate voltage level translation.

Note 5.8 This specification applies to all IPCI type inputs and tri-stated bi-directional PCI pins. Note 5.9 XI can optionally be driven from a 25MHz single-ended clock oscillator.
