MM54C42/MM74C42 BCD-to-Decimal Decoder General Description The MM54C42/MM74C42 one-of-ten decoder is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors. This decoder produces a logical ‘‘0’’ at the output corresponding to a four bit binary input from zero to nine, and a logical ‘‘1’’ at the other outputs. For binary inputs from ten to fifteen all outputs are logical ‘‘1’’.
