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 (I_0x, I_1x) 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.
