MC54/74F399
QUAD 2-PORT REGISTER
The MC54/74F399 is the logical equivalent of a quad 2-input multiplexer
feeding into four edge-triggered flip flops. A common Select input determines
which of the two 4-bit words is accepted. The selected data enters the flip-
flops on the rising edge of the clock. The MC54/74F399 is the 16-pin version
of the MC54/74F398, with only the Q outputs of the flip-flops available.

FUNCTIONAL DESCRIPTION
The MC54/74F398 is a high-speed quad 2-port register. It
type output register is fully edge-triggered. The Data inputs
will select 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-
(I , I ) 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.
