description/ordering information  
The ’AHC574 devices are octal edge-triggered D-type flip-flops that feature 3-state outputs designed  
specifically for driving highly capacitive or relatively low-impedance loads. These devices are particularly  
suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.  
On the positive transition of the clock (CLK) input, the Q outputs are set to the logic levels of the data (D) inputs.  
A buffered output-enable (OE) input places the eight outputs in either a normal logic state (high or low) or the  
high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly.  
The high-impedance state and the increased drive provide the capability to drive bus lines without interface or  
pullup components.
