SN54LS399 : The SN54 / 74LS398 and SN54 / 74LS399 are high-speed Quad 2-Port Registers. They select four bits of data from two sources (Ports) under the 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 in- put (CP). The 4-Bit RS type output register is fully edge-triggered. The Data inputs (I) and Select inputs (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 SN54 / 74LS398 has both Q and Q Outputs available. FUNCTION TABLE INPUTS OUTPUTS S I0 I1 Q I I XL Q* H I h XH L hX I L H h XhH *SN54 / 74LS.
