Digital Input/Output Card
IOD-144
-
This is a 144-bit full-size card. A Programmable Peripheral Interface chip, type 8255-5 provides three 8-bit ports (A, B, and C) for each 24-bit group. Each port can be independently programmed for either input or output. Port C can also be configured as two 4-bit ports. These cards fully implement Mode 0 of the 8255 PPI chip. (Consult the factory if you desire to operate in Mode 1.) Type LS245 bi-directional transceivers sink 24 mA (optionally 64 mA) and source 15 mA. These transceiver buffers provide hysteresis correction on inputs and added drive capability on outputs. The direction of the transceivers is set by software.
