The ratings in Table 23-1 define maximum conditions to which the MCF5272 may be subjected without
being damaged. However, the device cannot operate normally while exposed to these electrical extremes.
This device contains circuitry that protects against damage from high static voltages or electrical fields;
however, normal precautions should be taken to avoid application of voltages higher than maximum-rated
voltages to this high-impedance circuit. Reliability improves when unused inputs are tied to an appropriate
logic voltage level (GND or V_DD).
