MM54C42/MM74C42 BCD-to-Decimal Decoder
General Description
The MM54C42/MM74C42 one-of-ten decoder is a mono-
lithic complementary MOS (CMOS) integrated circuit con-
structed with N- and P-channel enhancement transistors.
This decoder produces a logical ‘‘0’’ at the output corre-
sponding 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’’.
