L-Tron

The PCI-1757UP is a 24-bit DI/O 1low profile PCI card. It meets the PCI standard REV.2.2 (universal PCI expansion card), and works with both 3.3V and 5V PCI slot. It provides users with 24 bits of parallel digital input/output, emulates mode 0 of the 8255 PPI chip, but the buffered circuits offer a higher driving capability than the 8255.
