† All typical values are at VCC = 5 V and TA = 25°C.

‡

∆|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.

§ In ANSI Standard EIA/TIA-422-B, VOC, which is the average of the two output voltages with respect to GND, is called output offset voltage, VOS.

NOTE 3: This applies for both power on and off; refer to ANSI Standard EIA/TIA-422-B for exact conditions.
