SN54/74LS398 QUAD 2-PORT REGISTER SN54/74LS399 The SN54 / 74LS398 and SN54 / 74LS399 are Quad 2-Port Registers. They are the logical equivalent of a quad 2-input multiplexer followed by a quad 4-bitedge-triggered register. A Common Select input selects between two 4-bit in-put ports (data sources). The selected data is transferred to the output registeron the LOW-to-HIGH transition of the Clock input. The SN54/ 74LS398 fea- QUAD 2-PORT REGISTER tures both Q and Q inputs, while the SN54 / 74LS399 has only Q outputs. · Select From Two Data Sources LOW POWER SCHOTTKY · Fully Positive Edge-Triggered Operation · Both True and Complemented Outputs on SN54/74LS398 · Input Clamp Diodes Limit High-Speed Termination Effects CONNECTION DIAGRAM DIP (TOP VIEW) V J SUFFIX CC Qd Qd Iod I1d I I 1c 0c Qc Qc CP CERAMIC 20 19 18 17 16 15 14 13 12 11 CASE 620-09 16 1 SN54 / 74LS398 N SUFFIX PLASTIC CASE 648-08 16 1 2 3 4 5 6 7 8 9 10 S
