Unless otherwise noted these limits are over the operating free-air temperature range.)

RECOMMENDED OPERATING CONDITIONS
DC ELECTRICAL CHARACTERISTICS(Over recommended operating free-air temperature range unless otherwise noted.)
NOTES: For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. All typical values are at VCC = 5V, Tamb = 25°C. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, IOS tests should be performed last.
