† For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.

‡ All typical values are at VCC = 5 V and TA = 25°C except for VOC, for which VCC is as stated under test conditions.

§

∆VOD and ∆|VOC| are the changes in magnitudes 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.

# Only one output should be shorted at a time, and duration of the short circuit should not exceed one second.
