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’’.
