All typical values are at VCC = 5V and TA = 25°C.
The minimum VOD2 with a 100Ω load is either 1/2 VOD1 or 2V, whichever is greater.
The algebraic convention, where the less positive (more negative) limit is designated as minimum, is used in this data sheet for common-mode output and threshold voltage levels only.
See TIA/EIA-485-A Figure 6-3.5, test termination measurement 2.
∆|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.
