Note 1

‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed Except for ‘‘Operating Temperature Range’’

they are not meant to imply that the devices should be operated at these limits The table of ‘‘Electrical Characteristics’’ provides conditions for actual device

operation

Note 2

Unless otherwise specified minmax limits apply across the

a

5V

Note 3

All currents into device pins shown as positive out of device pins as negative all voltages referenced to ground unless otherwise noted All values shown

as max or min on absolute value basis

Note 4

When measuring output drive current and switching response for the DS1678 and DS3678 a 15X resistor should be placed in series with each output This

resistor is internal to the DS1648DS3648 and need not be added
