MC68340 USER’S MANUAL

11-1

This device contains protective

circuitry against damage due to

high static voltages or electrical

fields; however, it is advised that

normal precautions be taken to

avoid application of any voltages

higher than maximum-rated

voltages to this high-impedance

circuit. Reliability of operation is

enhanced if unused inputs are

tied to an appropriate logic

voltage level (e.g., either GND

or V CC).

SECTION 11

ELECTRICAL CHARACTERISTICS

This section contains detailed information on power considerations, DC/AC electrical

characteristics, and AC timing specifications of the MC68340. Refer to Section 12

Ordering Information and Mechanical Data for specific part numbers corresponding to

voltage, frequency, and temperature ratings.

NOTES:

Permanent damage can occur if maximum ratings are exceeded. Exposure

to voltages or currents in excess of recommended values affects device

reliability. Device modules may not operate normally while being exposed to

electrical extremes.

Although sections of the device contain circuitry to protect against damage

from high static voltages or electrical fields, take normal precautions to

avoid exposure to voltages higher than maximum-rated voltages.

The following ratings define a range of conditions in which the device will operate without

being damaged. However, sections of the device may not operate normally while being

exposed to the electrical extremes.
