(NOTE)
1. Str_ above those lilted under "ABSOLUTE MAXIMUM RATINGS" may cause permanent damage to the device. Normal opera-
tion should be limited to those conditions specified under "ELECTRICAL CHARACTERISTICS -1" and "·2". The use beyond these
conditions may cause LSI's malfunction and at the same time affects devica reliability.
2. All voltages are with respect to GND.
3. Maximum Total Output Current is the total sum of output currents which can flow out or in simultaneously.
