Functional Description
The ’F398 and ’F399 are high-speed quad 2-port registers.
They 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 syn-
chronous with the LOW-to-HIGH transition of the Clock in-
put (CP). The 4-bit D-type output register is fully edge-trig-
gered. The Data inputs (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. The ’F398 has both Q and Q outputs.
