~BlillSROM Code ConvertersMM42300W/MM52300W hollerith to EBCDIC code convertergeneral descriptionlines to eight line binary encoded form suitablefor use by the ROM.For electrical, environmental and mechanical de-tails, refer to the MM4230/MM5230 data sheet.The MM42300W/MM5230QW 2048-bit MaS readonly memory has been programmed to convert the12 line Hollerith Code to the 8 line EBCDIC Code.Three TTL 4-input NAND gates and three TTLinverters are used to compress the 12 Hollerithtypical applicationHollerith to EBCDICconnection diagramDual-In-Line Package4 INPUT N~ND GATES AREDMJ4JOlVP!SDMi811TVPOS'»'"",;:;:::::I,-" 3'"IMODEICONrRO~UK UK HCDICOUTPUT.,~'r-8,-4 21r-.A.:-t..'r- ,6,_5 lOrA,"-,_I24f--Voo" " " , '" A,-2 2Jr-NCINPUT(..£ONE 11" "MM52l00W,M" 'f-8,-6 19r-A •.PONCHEDCARD'r-" " 'f-A,-322r-NC,8,-8 11r- ,!,.84-1 lsr-A),8._9 lGr-OGG8,_10".. 8._11..,PONCHES ,," NDTES" "L VS5~'1l DO 111%, Voo' GUO.
