This specification applies to all IS type inputs and tri-stated bi-directional non-PCI pins. Internal pull-
down and pull-up resistors add +/- 50
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.
This specification applies to all IPCI type inputs and tri-stated bi-directional PCI pins.
XI can optionally be driven from a 25MHz single-ended clock oscillator.
