DESCRIPTION
The M54/74HC76 is a high speed CMOSDUAL J-K
FLIP FLOP fabricated in silicon gate C2MOS tech-
nology. It has the same high speed performance of
LSTTL combined with true CMOS low power con-
sumption. Depending on with the logic level at the J
and K inputs this device changes state on thenega-
tive going transition of the clock pulse. CLEAR and
PRESET are independent of the clock and are ac-
complished by a logic low on the corresponding
input. All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.

(*) CPD isdefined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the followingequation. ICC(opr) = CPD • VCC • fIN + ICC/2 (per FLIP/FLOP)
