Note
The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaran-
teed The device should not be operated at these limits The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation

Not more than one output should be shorted at a time
Note 3
ICC is measured with all outputs open R0 inputs grounded following momentary connection to 45V and all other inputs grounded
Note 4
QA outputs are tested at IOL e max plus the limit value of IIL for the B input This permits driving the B input while maintaining full fan-out capability
