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 These specifications apply for 4 5V s VCC s 5 5V 15V s VCM s 15V and 55 C s TA s a125 C for the DS7820 or 0 C s TA s a70 C for the
DS8820 unless otherwise specified typical values given are for VCC 5 0V TA 25 C and VCM 0 unless stated differently
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 The specifications and curves given are for one side only Therefore the total package dissipation and supply currents will be double the values given when
both receivers are operated under identical conditions
