pci-1757up is a 24-channel di/o low profile pci card that meets the pci standard rev.2.2 (universal pci expansion card). the card also works with 3.3 v and 5 v pci slots, and provides you with 24 parallel digital input/output channels that emulate mode 0 of the 8255 ppi chip. however, the buffered circuits offer a higher driving capability than the 8255. |
