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 b55 Cto a125 C temperature range for the DM2502 DM2503 and DM2504 and across the
0 Cto a70 C range for the DM2502C DM2503C and DM2504C All typicals are given for VCCe50V and TAe25 C
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
Only one output at a time should be shorted
