MM54HC42/MM74HC42BCD-to-Decimal DecoderGeneral DescripTIonThis decoder uTIlizes advanced silicon-gate CMOS technology.Data on the four input pins select one of the 10 outputscorresponding to the value of the BCD number on the inputs.An output will go low when selected, otherwise it remainshigh. If the input data is not a valid BCD number alloutputs will remain high. The circuit has high noise immunityand low power consumpTIon usually associated with CMOScircuitry, yet also has speeds comparable to low powerSchottky TTL (LS-TTL) circuits, and is capable of driving 10LS-TTL equivalent loads.
