Functional Description  
Truth Tables  
The ABT16373 contains sixteen D-type latches with  
TRI-STATE standard outputs. The device is byte controlled  
with each byte functioning identically, but independent of the  
other. Control pins can be shorted together to obtain full  
16-bit operation. The following description applies to each  
byte. When the Latch Enable (LEn) input is HIGH, data on  
the Dn enters the latches. In this condition the latches are  
transparent, i.e., a latch output will change states each time  
its D input changes. When LEn is LOW, the latches store in-  
formation that was present on the D inputs a setup time pre-  
ceding the HIGH-to-LOW transition of LEn. The TRI-STATE  
standard outputs are controlled by the Output Enable (OEn)  
input. When OEn is LOW, the standard outputs are in the  
2-state mode. When OEn is HIGH, the standard outputs are  
in the high impedance mode but this does not interfere with  
entering new data into the latches.
