(1) All typical values are at V_CC = 5V and T_A = 25°C.

(2) The minimum V_OD2 with a 100Ω load is either 1/2V_OD1 or 2V, whichever is greater.

(3) Δ|V_OD| and Δ|V_OC| are the changes in magnitude of V_OD and V_OC, respectively, that occur when the input is changed from a high level to a low level.

(4) In ANSI Standard EIA/TIA-422-B, V_OC, which is the average of the two output voltages with respect to ground, is called output offset voltage, V_OS.

(5) See EIA Standard RS-485, Figures 3-5, Test Termination Measurement 2.
