These 8-bit 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.

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 levels that were  
set up at the D inputs.
