Description  
Functional Diagram  
The CD54AC373/3A and CD54ACT373/3A are octal trans-  
parent three-state latches that utilize the Harris Advanced  
CMOS Logic technology. The outputs are transparent to the  
inputs when the Latch Enable (LE) is HIGH. When the Latch  
Enable (LE) goes LOW, the data is latched. The Output  
Enable (OE) controls the three-state outputs. When the Out-  
put Enable (OE) is HIGH, the outputs are in the high-imped-  
ance state. The latch operation is independent of the state of  
the Output Enable.
