SECTION 10
ELECTRICAL CHARACTERISTICS
This section provides the thermal characteristics and electrical specifications for the
MC68020/EC020. Note that the thermal and DC electrical characteristics are listed
separately for the MC68020 and the MC68EC020. All other data applies to both the
MC68020 and the MC68EC020 unless otherwise noted.

The device contains circuitry to
protect the inputs against damage
due to high static voltages or electric
fields; however, normal precautions
should be taken to avoid application
of voltages higher than maximum-
rated voltages to these high-
