Functional Description  
The ’ACTQ841 consists of ten D-type latches with  
TRI-STATE outputs. The flip-flops appear transparent to the  
data when Latch Enable (LE) is HIGH. This allows asynchro-  
nous operation, as the output transition follows the data in  
transition.

On the LE HIGH-to-LOW transition, the data that meets the  
setup and hold time is latched. Data appears on the bus  
when the Output Enable (OE) is LOW. When OE is HIGH the  
bus output is in the high impedance state.
