description  
The ’AHCT574 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.  
OE does not affect internal operations of the flip-flop. Old data can be retained or new data can be entered while  
the outputs are in the high-impedance state.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
The SN54AHCT574 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74AHCT574 is characterized for operation from –40°C to 85°C.
