Functional Description  
Function Table  
The ’AC/ACT399 is a high-speed quad 2-port register. It se-  
lects four bits of data from either of two sources (Ports) un-  
der control of a common Select input (S). The selected data  
is transferred to a 4-bit output register synchronous with the  
LOW-to-HIGH transition of the Clock input (CP). The 4-bit  
D-type output register is fully edge-triggered. The Data in-  
puts (I0x, I1x) and Select input (S) must be stable only a setup  
time prior to and hold time after the LOW-to-HIGH transition  
of the Clock input for predictable operation.
