National Semiconductor DM74185A

the DM74184 is analogous to the algorithm a Shift BCD number right one bit and examine each decade Subtract three from each 4-bit decade containing a binary value greater than seven b Shift right examine and correct after each shift until the least significant decade contains a number smaller than eight and all other converted decades contain zeros In addition to BCD-to-binary conversion the DM74184 is programmed to generate BCD 9’s complement or BCD 10’s complement Again in each case one bit of the complement code is logically equal to one of the BCD bits therefore these complements can be...
