QUAD 2-PORT REGISTER  
The SN54/74LS398 and SN54/74LS399 are Quad 2-Port Registers. They  
arethelogicalequivalentofaquad2-inputmultiplexerfollowedbyaquad4-bit  
edge-triggered register. A Common Select input selects between two 4-bit in-  
putports(datasources). Theselecteddataistransferredtotheoutputregister  
on the LOW-to-HIGH transition of the Clock input. The SN54/74LS398 fea-  
tures both Q and Q inputs, while the SN54/74LS399 has only Q outputs.
