All typical values are at V

= 25°C except for V
OC
, for which V

is as stated under test conditions.
‡
∆|V
OD
| and ∆|V
OC
| are the changes in magnitudes of V
OD
and V
OC
, respectively, that occur when the input is changed from a high level to a low
level.
§
In ANSI Standard EIA/TIA-422-B, V
OC
, which is the average of the two output voltages with respect to GND, is called output offset voltage, V
OS
.
¶
Only one output should be shorted at a time, and duration of the short circuit should not exceed one second.
