Above, “5 V” refers to a 3-V buffer with 5-V tolerant circuit. Therefore, it is possible to have a 5-V connection for an

external bus, but the output level will be only up to 3 V, which is the VDD voltage. Similarly, “5 V PCI” above refers to a

PCI buffer that has a 5-V tolerant circuit, which meets the 3-V PCI standard; it does not refer to a PCI buffer that

meets the 5-V PCI standard.
