DESCRIPTION

The M54/74HC76is a high speedCMOSDUAL J-K
FLIP FLOP fabricated in silicon gate C2MOStech­nology. Ithas the same high speedperformance of
LSTTL combined with true CMOS low power con­sumption.Depending on with the logiclevelat theJ
and Kinputsthisdevice changes stateon thenega­tive going transition of the clock pulse. CLEAR and
PRESETare independent of theclock and areac­complished by a logic low on the corresponding
input.Allinputsare equipped withprotectioncircuits
against static discharge and transient excess volt­age.
