Note 1
‘‘Absolute Maximum Rating’’ are those values beyond which the safety of the device cannot be guaranteed 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 b55 Cto a125 C temperature range for the DS7880 and across the 0 Cto a70 C range for
the DS8880 All typical values are for TA e 25 C and VCC 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 or absolute value basis
Note 4
In all applications transient segment output current must be limited to 50 mA This may be accomplished in dc applications by connecting a 22k resistor
from the anode-supply filter capacitor to the display anode or by current limiting the anode driver in multiplex applications
Note 5
For saturation mode the segment output currents are externally limited and ratioed
