Remarks 1. “5 V tolerant“ means that the buffer is 3 V buffer with 5 V tolerant circuit.
2. “5 V PCI” indicates a PCI buffer, which complies with the 3 V PCI standard, has a 5 V tolerant circuit. It
does not indicate that this buffer fully complies with 5 V PCI standard. However, this function can be
used for evaluating the operation of a device on a 5 V add-in card.
3. The signal marked as “(I/O)” in the above table operates as I/O signals during testing. However, they
do not need to be considered in normal use.
