(1) All typical values are at VCC = 5V and TA = 25°C.
(2) The minimum VOD2 with a 100Ω load is either 1/2 VOD1 or 2V, whichever is greater.
(3) ∆|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.
(4) In ANSI Standard EIA/TIA-422-B, VOC, which is the average of the two output voltages with respect to ground, is called output offset voltage, VOS.
(5) See Figure 6-3 of EIA Standard RS-485.
