48 bit digital I/O lines (2 groups)
Group emulates a 8225 PPI mode 0
Buffered circuits for higher drive capacity than 8255
Bit 0 of port C can generate an interrupt to IRQ 2,3,4,5,6 or 7
Interrupt trigger on rising/falling edge
Output status read back
Pin-compatible with Opto-22 I/O module racks
Transfer rates: 300 KB/sec (typical)
Digital output: Logic level 0: 0.5V max @ 24mA Logic level 1: 2.0V min @ 15mA
Digital input: Logic level 0: 0.8V Max
Logic level 1:2.0V min
