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 DS96F172C/DS96F174C. All typicals are given for VCC = 5V and TA = 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:Δ|VOD | andΔ|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. Order Number: DS96F172CN DS96F174CJ DS96F174CN www.national.com3
