5. When VD1 is powered from 3.3 Volts, all ISA bus input pins, except DRQA, must also be 3.3 Volts.
Operation beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
DRQA is internally powered from the VDF supply and must have a 5 Volt interface. To use DRQA in
a 3.3 Volt application, a level translator is needed.
