description/ordering information  
These octal edge-triggered D-type 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.

On the positive transition of the clock (CLK) input,  
the Q outputs are set to the complements of the  
logic levels set up at the data (D) inputs.

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  
increased drive provide the capability to drive bus  
lines without need for interface or pullup  
components.

OE does not affect internal operations of the flip-flops. Old data can be retained or new data can be entered  
while the outputs are in the high-impedance state.
