Functional Description
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 (I
0x,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.
