AC Electrical Characteristics

Note 1 Absolute Maximum Ratings indicate limits beyond which damage to the device may occur Operating Ratings indicate conditions for which the device is
functional These ratings do not guarantee specific performance limits however For guaranteed specifications and test conditions see the Electrical Characteris-
tics The guaranteed specifications apply only for the test conditions listed Some performance characteristics may degrade when the device is not operated under
the listed test conditions
Note 2 All voltages are measured with respect to GND (GND
Note 3 When the input voltage (V
limited to 25 mA or less The 50 mA package input current limits the number of pins that can safely exceed the power supplies with an input current of 25 mA to
two
Note 4 The maximum power dissipation must be derated at elevated temperatures and is dictated by T
allowable power dissipation at any temperature is P
(PLCC) package is 55 C W i
