* Maximum Ratings are those values beyond which damage to the device may occur.
1. Connecting any input terminal to voltages greater than V+ or less than GND may cause destructive latch–up. It is recommended that no inputs
from sources operating from external supplies be applied prior to ”power up” of the MC7660.
