† All typical values are at VCC = 5 V and TA = 25°C.
‡ The minimum VOD2 with a 100-Ω load is either 1/2 VOD1 or 2 V, whichever is greater.
§
∆|V
OD| and
∆|V
OC| 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.
¶ 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.
