They are not meant to imply that the devices should be operated at these limits. The tables of “Electrical Characteristics” provide conditions for actual device operation. Note 3: Unless otherwise specified min/max limits apply across the 0˚C to +70˚C range for the DS96F174C. All typicals are given for V CC = 5V and T A = 25˚C. Note 4: All currents into the device pins are positive; all currents out of the device pins are negative. All voltages are reference to ground unless otherwisespecified. Note 5: ∆|VOD| and ∆|VOC| are the changes in magnitude of V OD and VOC respectively, that occur when the input is changed from a high level to a low level. Note 6: In EIA-422A and EIA-485 standards, V OC, which is the average of the two output voltages with respect to ground, is called output offset voltage, V OS. Note 7: Only one output at a time should be shorted. Note 8: For more information see Application Bulletin, contact Product Marketing.
