Connecting I/O Signals

The I/O circuits of interface blocks of this board are illustrated in Figure 3.5. Signals are LVTTL levels

and positive logic. None of the signals is pulled up.

Figure 3.5. I/O Circuit

CAUTION

-

Take care not to short the outputs to digital ground as this may cause a fault.

-

If connecting pull-up resistors to the outputs, use a resistor of approximately 10k

Ω

and pull-up to the

5V power supply, or use a resistor of approximately 4.7k

Ω

and pull-up to the 3.3V power supply.
