Description

The M54/74HC564andM54HC574 arehighspeed CMOSOCTALD-TYPEFLIPFLOPWITH3-STATE 2 OUTPUTS fabricated with in silicon gate C MOS technology. They have the same high speed per- formanceof LSTTLcombined with true CMOSlow ower comsuption. These8-bit D-typeflip-flops are ontrolledbyaclockinput(CK)andanouputenable nput(OE).Onthepositivetransitionoftheclock,the outputswillbesettothelogicstatethatweresetup t the D inputs (HC574) or their omplement(HC564).
