Electrical Characteristics
over recommended operating free air temperature range (unless otherwise noted)
Note 7: All typicals are at V
Note 8: 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,
where shorting the outputs to ground may cause the outputs to change logic state an equivalent test may be performed where V
and maximum limits reduced by one half from their stated values. This is very useful when using automatic test equipment.
