DIO Guidelines
Consider the following guidelines when using the DIO lines.
V
OLTAGE
The DIO lines are 3.3 V Low-voltage TTL (LVTTL) compatible DIOs capable of
sourcing/sinking an absolute maximum of 25 mA of current. Level shifting or current limiting is
necessary when connecting signals with different voltage rails.
CAUTION:
Do not connect the DIO signals to ex5 V devices; doing so will damage the DIO device
and void the warranty.
