DESCRIPTION
The M54/74HC109 is a highspeed CMOSDUAL JK FLIP-FLOP WITH PRESET AND CLEAR fabricated in silicon gate C2MOStechnology.
It has the same high speed performance of LSTTL
combined with true CMOSlowpower consumption.
In accordance with the logic level on the J and K
inputisdevicechangesstateonpositivegoingtransitionsof the clock pulse. CLEAR and PRESETare
independent ofthe clockandaccomplished bya low
logic level on the corresponding input.
All inputs are equipped with protection circuits
against static discharge and transient excess voltage.
