 Question:
IOF register and Xf pins: At reset, a customer wants to
have both pins pulled low with a 330 ohm resister. Does
this cause any problem? Can the output drivers for these
pins drive this load?
Answer: The maximum drive current, IOH, is only 300uA.
The required current to drive a 330 ohm resister to 2.4 V
is about 7.3 mA. The resistance would need to be at least
8 kohm for the driver to drive a TTL voltage level.
