Digital I/O Lines
These cards provide 16 bits of parallel digital input/output. They can be programmed as
inputs or outputs on the two 8-bit ports designated Ports A and B.
Each I/O line is buffered by a type 74LVC8T245 buffer transceiver capable of sourcing
or sinking 32mA (w/ 5V VCCIO), or 24mA (w/ 3.3V VCCIO). Pull-ups on the card assure
that there are no erroneous outputs at power up. The lines initialize in the input mode.
