description/ordering information  
These 8-bit flip-flops feature 3-state outputs  
designed specifically for driving highly capacitive  
or relatively low-impedance loads. The devices  
are particularly suitable for implementing buffer  
registers, I/O ports, bidirectional bus drivers, and  
working registers.  
GND  
The eight flip-flops of the AC574 devices are  
D-type edge-triggered flip-flops. On the positive  
transition of the clock (CLK) input, the Q outputs  
are set to the logic levels set up at the data (D)  
inputs.  
SN54AC574 . . . FK PACKAGE  
(TOP VIEW)  
A buffered output-enable (OE) input can be used  
to place the eight outputs in either a normal  
logic state (high or low logic levels) 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 in a bus-organized system without need  
for 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.
