Functional Description
The AC/ACT399 is a high-speed quad 2-port register. It
selects four bits of data from either of two sources (Ports)
under 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 inputs (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.
