Description  
• Buffered Inputs  
The ’HC534, ’HCT534, ’HC564, and ’HCT564 are high speed

technology. They possess the low power consumption of stan-  
dard CMOS integrated circuits, as well as the ability to drive  
15 LSTTL loads. Due to the large output drive capability and  
the three-state feature, these devices are ideally suited for  
interfacing with bus lines in a bus organized system. The two  
types are functionally identical and differ only in their pinout  
arrangements.

• Fanout (Over Temperature Range)  
The ’HC534, ’HCT534, ’HC564, and ’HCT564 are positive  
edge triggered flip-flops. Data at the D inputs, meeting the  
setup and hold time requirements, are inverted and trans-  
ferred to the Q outputs on the positive going transition of the  
CLOCK input. When a high logic level is applied to the OUT-  
PUT ENABLE input, all outputs go to a high impedance state,  
regardless of what signals are present at the other inputs and  
the state of the storage elements.
