Note 2: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. 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 0C to +70C range for the DS96F174C. All typicals are given for VCC = 5V and TA = 25C.
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 otherwise specified.
Note 5:
|VOD| and |VOC| are the changes in magnitude of VOD 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, VOC, which is the average of the two output voltages with respect to ground, is called output offset voltage, VOS.
Note 7: Only one output at a time should be shorted.
Note 8: For more information see Application Bulletin, contact Product Marketing.
