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

Note 1
All typicals are at VCC e 5V TA e 25 C
Note 2
Not more than one output should be shorted at a time and the duration should not exceed one second
Note 3
Quiescent ICC is measured (after clearing) with 24V applied to all clear and A inputs B inputs grounded all outputs open CEXT e 002 mF and
REXT e 25 kX
Note 4
ICC is measured in the triggered state with 24V applied to all clear and B inputs A inputs grounded all outputs open CEXT e 002 mF and REXT e 25 kX
Note 5
With all outputs open and 45V applied to all data and clear inputs ICC is measured after a momentary ground then 45V is applied to the clock
