  54F 74F193 Up Down Binary Counter
  with Separate Up Down Clocks
  General Description
  The 'F193 is an up down modulo-16 binary counter Sepa-                                Individual preset inputs allow the circuit to be used as a
  rate Count Up and Count Down Clocks are used and in                                   programmable counter Both the Parallel Load (PL) and the
  either counting mode the circuits operate synchronously                               Master Reset (MR) inputs asynchronously override the
  The outputs change state synchronously with the LOW-to-                               clocks
  HIGH transitions on the clock inputs Separate Terminal
  Count Up and Terminal Count Down outputs are provided                                 Features
  that are used as the clocks for subsequent stages without                             Y   Guaranteed 4000V minimum ESD protection
  extra logic thus simplifying multi-stage counter designs
