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 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 VO e 225V and 2125V for DM54 and

DM74 series respectively with the minimum and maximum limits reduced by one half from their stated values This is very useful when using automatic test

equipment

Note 3

With all outputs open ICC is measured with the Q and Q outputs high in turn At the time of measurement the clock is grounded
