description/ordering information  
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 respond to the data (D) inputs. When LE is low, the  
outputs are latched to retain the data that was set up.  
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 interface or pullup components.
