Functional Description  
The ’F533 contains eight D-type latches with TRI-STATE  
output buffers. When the Latch Enable (LE) input is HIGH,  
data on the D inputs enters the latches. In this condition  
n
the latches are transparent, i.e., a latch output will change  
state each time its D input changes. When LE is LOW, the  
latches store the information that was present on the D in-  
puts a setup time preceding the HIGH-to-LOW transition of  
LE. The TRI-STATE buffers are controlled by the Output  
Enable (OE) input. When OE is LOW, the buffers are in the  
bi-state mode. When OE is HIGH the buffers are in the high  
impedance mode but this does not interfere with entering  
new data into the latches.
