DESCRIPTION

The M54/74HC73is a high speedCMOSDUAL J-K
FLIP FLOPWITHCLEAR fabricated in silicongate
C2MOStechnology. Ithasthesamehighspeedper­formance of LSTTL combined with trueCMOS low
power consumption. Depending on the logic level
applied toJand K inputs, this device changes state
on thenegative going transition ofclock input pulse
(CK). The clear function is accomplished inde­pendentlyoftheclockconditionwhen the clearinput
(CLR)is taken low. Allinputsare equippedwithpro­tectioncircuits againststaticdischarge and transient
excess voltage.
