MM54C42 MM74C42 BCD-to-Decimal Decoder March 1988 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’’ Y Y Y High noise immunity Low power Medium speed operation 0 45 VCC (typ ) 50 nW (typ ) 10 MHz (typ ) with 10V VCC
