Note: There are no restrictions on the relationship of each voltage level in comparison with the others (regarding
which is higher or lower), as long as the voltages applied to VCC, VS1, VS2, and IN1 through IN4 are within the
limits set by the absolute maximum ratings. (Ex: VCC=3V, VS1, 2=2V, IN1 to IN4=5V)
UTC assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or
other parameters) listed in products specifications of any and all UTC products described or contained
herein. UTC products are not designed for use in life support appliances, devices or systems where
