DESCRIPTION
The M54/74HC109 is a high speed CMOS DUAL J-
K FLIP-FLOP WITH PRESET AND CLEAR fabri-
cated in silicon gate C2MOS technology.
It has the same high speed performance of LSTTL
combined with true CMOS low power consumption.
In accordance with the logic level on the J and K
input is device changes state on positive going tran-
sitions of the clock pulse. CLEAR and PRESET are
independent of the clock and accomplished by a low
logic level on the corresponding input.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.

(*) CPD is defined 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 following equation. ICC(opr) = CPD VCC fIN + ICC/2 (per Flip-flop)
