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 Voltage values are with respect to network ground terminal unless otherwise specified
Note 3 The voltage between two emitters of a multiple-emitter transistor
Note 4 The maximum voltage which should be applied to any output when it is in the ‘‘OFF’’ state
Note 5 Both halves of these dual circuits may conduct rated current simultaneously however power dissipation averaged over a short time interval must fall within
the continuous dissipation rating
Note 6 Unless otherwise specified min max limits apply across the b55 C to a125 C temperature range for the DS55450 series and across the 0 C to a70 C
range for the DS7545X series All typicals are given for V_CC e a5V and T_A e 25 C
Note 7 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
