Display Drivers DM5441A/DM7441A BCD to decimal decoder/nixie* driver general description The DM5441AIDM7441A is monolithic blnarycoded-decimal to decimal decoder. The BCD number to be decoded IS applied to the four input lines; and the unique output correspond Ing to the decimal equivalent of the input number falls to a logical 0 level. Outputs are designed to drive gas-filled-readout (Nixle*) tubes but are also able to operate with other low current lamps and re·lays. An over-range feature provides that if binary numbers between 10 and 15 are applied to the input the least significant bit of these numbers (0 through 5) will be decoded on the output. connection diagram .N.Dual-I n-Line and Flat Package typical applications Nixie* Readout s' logic table Order Number DM5441AJ or DM7441AJ See Package 17 Order Number DM7441N Se.
