General Description

The 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”.
