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’’
