A common Select input determines which of the two 4-bit words is accepted. The selected data enters the flipflops on the rising edge of the clock. The ’F399 is the 16-pin version of the ’F398, with only the Q outputs of the flip-flops available.

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 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. The ’F398 has both Q and Q outputs.
