description  
The CY74FCT2574T is a high-speed, low-power, octal D-type flip-flop featuring separate D-type inputs for each  
flip-flop. On-chip termination resistors at the outputs reduce system noise caused by reflections. The  
CY74FCT2574T can replace the CY74FCT574T to reduce noise in an existing design. This device has 3-state  
outputs for bus-oriented applications. A buffered clock (CP) and output-enable (OE) inputs are common to all  
flip-flops. The CY74FCT2574T is identical to the CY74FCT2374T, except that on the CY74FCT2574T all  
outputs are on one side of the package and all inputs are on the other side. The flip-flops in the CY74FCT2574T  
storethestateoftheirindividualDinputsthatmeetthesetup-timeandhold-timerequirementsonthelow-to-high  
CP transition. When OE is low, the contents of the flip-flops are available at the outputs. When OE is high, the  
outputs are in the high-impedance state. The state of OE does not affect the state of the flip-flops.  
This device is fully specified for partial-power-down applications using I . The I circuitry disables the outputs,

off  
preventing damaging current backflow through the device when it is powered down.
