DM7441A BCD to Decimal Decoder
The DM7441A is a BCD-to-decimal decoder designed to drive gas-filled NIXIE tubes. The device is also capable of driving other types of low-current lamps and relays. An over-range decoding feature provides that if binary numbers between 10 and 15 are applied to the input, the least significant bit (0-5) will be decided on the output. Input clamp diodes are also provided to clamp negative-voltage transitions in order to minimize transmission-line effects.
