DIO-144

Introducción

The DIO-144 Provides 144 TTL digital I/O lines. The DIO-144 emulates 8255 mode 0 and has a increased output current of 15 mA (source) and 64 mA (sink) , allowing it to control LED, relay, etc. The DIO-144 consists of eighteen 8 bit bi-directional ports and 2 input lines for interrupt enable and interrupt. The 8 bit port are named port A(PA),port B(PB) ,port C(PC). The port C can be split into two four bit. All port are configured as inputs upon power-up or reset. The DIO-144 use 4 I/O address. The base address is selectable from 200 to 3FF hex. The interrupt signal can be connected to any of the interrupt levels 2 through 7 .
