DESCRIPTION

The M54/74HC74 is a high speed CMOS DUAL D
TYPE FLOP WITH PRESET AND CLEAR fabri­cated in silicon gate C2MOS technology.It has the
same high speed performance of LSTTL combined
withtrueCMOSlowpowerconsumption.Asignal on
the DINPUT istransferred totheQ OUTPUTduring
the positive going transition of the clock pulse.
CLEARand PRESET are independent of the clock
andaccomplished byalowon theappropriate input.
All inputs are equipped with protection circuits
against static discharge and transient excess volt­age.
