description  
These octal transparent D-type latches feature  
3-state outputs designed specifically for driving  
highly capacitive or relatively low-impedance  
loads. They are particularly suitable for  
implementing buffer registers, I/O ports,  
bidirectional bus drivers, and working registers.

While the latch-enable (LE) input is high, the Q  
outputs follow the data (D) inputs. When LE is  
taken low, the Q outputs are latched at the logic  
levels set up at the 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) or a 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  
latches. Old data can be retained or new data can  
be entered while the outputs are off.
