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 DS7837 and across the 0 C to a70 C range for
the DS8837 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 Only one output at a time should be shorted
Note 5 Fan-out of 10 load C_LOAD e 15 pF total Measured from V_IN e 1 3V to V_OUT e 1 5V V_IN e 0V to 3V pulse
Note 6 Fan-out of 10 load C_LOAD e 15 pF total Measured from V_IN e 2 3V to V_OUT e 1 5V V_IN e 0V to 3V pulse
Note 7 Fan-out of 10 load C_LOAD e 15 pF total Measured from V_IN e 1 5V to V_OUT e 1 5V V_IN e 0V to 3V pulse
