(1) All typical values are at VCC = 5 V and TA = 25°C.
(2) The minimum VOD specification may not fully comply with ANSI RS-485 at operating temperatures below 0°C. System designers should take the possibly lower output signal into account in determining the maximum signal-transmission distance.
(3) Δ|VOD| and Δ|VOC| are the changes in the steady-state magnitude of VOD and VOC, respectively, that occur when the input is changed from a high level to a low level.
