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 min max limits apply across the b55 C to a125 C temperature range for the DS16149 and DS16179 and across the 0 C to
a70 C range for the DS36149 and DS36179 All typical values are for T_A e 25 C and V_CC e 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 DS16179 and DS36179 a 15 X resistor should be placed in series with each output
This resistor is internal to the DS16149 DS36149 and need not be added
