Electrical Characteristics

over recommended operating free air temperature range (unless otherwise noted)

Note 7: Not more than one output should be shorted at a time, and the duration should not exceed one second. For devices, with feedback from the outputs,

and maximum limits reduced by one half from their stated values. This is very useful when using automatic test equipment.
